Eatin’ Vegan…Cajun Portobello Sandwich w/Avocado and Remoulade

Vegetarian, omnivore, vegan, locavore, flexitarian…the list goes on and on.  It seems the media as of late is obsessed with defining how we eat.   The parameters of our dinner tables now have labels on them and it’s getting a little chaotic.  I respect those whose diet reflects their values and beliefs, but I am interested in why now with the moral upswing?  Is it the due to the open door of such outlets like YouTube and Twitter that have suddenly brought light to the conditions that farmed animals have come to expect?  Is it the “Ah Ha” moment that many have experiencing after reading a Michael Pollan non-fiction eye-opener and therefore vow to eat more vegetables?  I think it is a combination of all the above, intertwined with the realization of the big picture.    The picture: You are what you eat and yes, responsible for how it got to your plate.

As I call the subtitle of this blog, “How I TRY to eat locally and not insanely”.  And I mean it.  I try to eat with my morals on board and teach my children where food really comes from.  And in that effort, I have come to check out a way of eating I would never had before…vegan.  I recently read the The Conscious Cook: Delicious Meatless Recipes That Will Change the Way You Eat by Tal Ronnen.  The recipe for portobello mushrooms caught my attention, as well as some other recipes that I will be sure to try.  I gave it a whirl and found it to be truly a tasty sandwich.  Although the next time I make it, I don’t think I will slice the mushrooms.  I think keeping them whole might give the sandwich a little more heft and bite.  The remoulade sauce is excellent and makes the dish.  It would go well with many other dishes.

Cajun Portobello Sandwich w/Avocado and Remoulade 

Pinch of sea salt
1/4 cup extra-virgin olive oil
2 shallots, chopped
2 garlic cloves, minced
2 to 3 tablespoons low-salt Cajun seasoning, divided use
1/2 cup dry white wine
1 1/2 tablespoons white wine vinegar
4 large portobello mushrooms, stemmed, gills removed, cut on the bias into 1/4-inch slices

About 1/4 cup rémoulade (recipe follows)
4 soft sandwich rolls, split
4 to 8 romaine lettuce leaves, rinsed and dried
1 large tomato, thinly sliced
1 ripe avocado, peeled, pit removed and sliced

1 cup vegan mayonnaise
1 tablespoon ketchup
1 tablespoon Dijon mustard
1 teaspoon hot sauce
1 teaspoon vegan Worcestershire sauce
1 tablespoon freshly squeezed lemon juice
1/2 teaspoon sea salt
2 teaspoons capers, minced
2 teaspoons minced shallot
1 teaspoon minced fresh parsley
2 teaspoons minced red bell pepper

For the mushrooms: Place a large pot over medium heat. Sprinkle the bottom with a pinch of salt and heat for 1 minute. Add the oil and heat for 1 minute, being careful not to let it smoke. This will create a nonstick effect.

Add the shallots and garlic and cook for 3 to 4 minutes, until softened. Add 1 tablespoon of the Cajun seasoning, along with the wine, vinegar and 1 cup water. Bring to a boil, then lower the heat and simmer for 20 minutes.

Add the mushrooms and cook for 1 minute. Pour the mushrooms and liquid into a shallow container, cover and set aside to marinade for 1 hour.

Remove the mushrooms from the marinade and press between paper towels or in a cotton dish towel to remove the excess marinade, then sprinkle with the remaining Cajun seasoning, pressing the seasoning into both sides of the mushroom slices. Discard the marinade.

In a cast-iron skillet over medium high heat, cook the mushrooms in a single layer (you may have to do this in two batches) until blackened, 2 to 3 minutes on each side. Remove to a plate.

To assemble: Spread a spoonful of the rémoulade on one half of each roll. Top each with 1 or 2 lettuce leaves and a few slices of tomato and avocado. Divide the mushroom slices among the rolls. Close each sandwich, cut in half and serve.

Makes 4 sandwiches.

For the rémoulade: Place mayonnaise, ketchup, mustard, hot sauce, Worcestershire sauce, lemon juice, salt, capers, shallot, parsley and pepper in a food processor or blender and blend on high for 1 minute. Store covered in the refrigerator for up to 1 week.

Makes 1 1/4 cups.

From “The Conscious Cook: Delicious Meatless Recipes That Will Change the Way You Eat” by Tal Ronnen


Yes, I will eat locally raised meat from time to time, as I just can’t bypass some dishes.  But opening up my eyes to enjoying a meal that did not involve animals in any way…for one night I wasn’t just human…I was humane.  And that’s a label we all should want to have at one point or another.

    I have been on a HUGE broccoli salad kick. I always have a container of it in the fridge ready to go. My favorite ingredients to go into the salad are red onions, raisins, and sunflower seeds. Mayonnaise grosses me out more than words can express, so I found some very light, barely dairy stuff, and I use hardly enough of it to dress the salad. My husband will even eat a few bites of it. I’m claiming victory.

    Other than that, I’ve been focused on mastering my ice cream maker. I have a batch of lemon sorbet ripening in the freezer now.

      The brocolli salad sounds refreshing for the summer, in addition to the sorbet. Pls send me the sorbet recipe. I have a easy good recipe for a key lime sorbet, but I keep forgetting to put the freezer bowl in freezer. I’ve been stressed out lately and when I stress I bake/cook.
