Summary

Oyster mushrooms stand in for meat or seafood in this comfort-style sandwich that hails from Louisiana. The mushrooms make the ideal substitution due to their meaty texture and delicate flavor, taking on the seasonings you add to them. When breaded then baked, they transform into a crispy delight that, when paired with all the fixings and wrapped in a whole grain baguette, tastes exquisite!

Oyster Mushroom Po’ Boy

Ingredients

Flax Egg
 2 tbsp flax meal
 6 tbsp water
Oyster Mushrooms
 6 oz King oyster mushrooms (approximately 2 cups or 4–6 large mushrooms)
 ¼ cup organic cornmeal
 ¼ cup organic oat flour (or almond meal)
 2 tsp Old Bay Seasoning (store bought or homemade, see Chef’s Notes)
 1 batch Easy Vegan Mayo (link in Chef’s Notes)
 1 organic whole grain baguette (cut into 2 5” pieces of baguette)
 pickles (homemade or low sodium store-bought, to taste)
 1 small organic tomato (sliced)
 1 handful organic arugula
 1 lemon (cut in half)

Directions

1

Preheat the oven to 450 degrees F and line a baking sheet with parchment paper.

2

Add the flax meal and water to a large bowl. Whisk and set aside.

3

Gently clean the mushrooms with a clean damp towel. Remove any hard areas of the stem. Soft areas of the stem are fine to leave.

4

Add the cornmeal, oat flour, and Old Bay seasoning to a large bowl and mix to combine.

5

Dip each oyster mushroom into the flax egg then coat the mushroom in the cornmeal mixture. Place on the baking sheet. Do the same with the remaining mushrooms, spacing them on the baking sheet evenly.

6

Bake for 20 minutes, flipping halfway through.

7

Once finished baking, assemble your sandwiches: Spread 1–2 Tbsps of the vegan mayo, on each side of the bread. Add several sprigs of arugula, 2–3 slices of tomato, 2–3 pickles.

8

Divide the oyster mushrooms between the two slices of whole grain baguette, squeeze a little lemon over top, and enjoy!

Chef's Notes

Substitutions
Substitute another creamy plant-based sauce for the vegan mayo.

Use another leafy green in place of arugula.

Prep Ahead
Make the Easy Vegan Mayo ahead of time and store in an airtight container in the refrigerator for up to 5 days.

Make your own DIY Old Bay: Mix together 1 teaspoon of celery seed, ¼ teaspoon of salt (optional), ½ teaspoon sweet paprika, ¼ teaspoon smoked paprika, ⅛ tsp ground black pepper, ⅛ teaspoon cayenne pepper (optional), ¼ teaspoon ground mustard, ⅛ teaspoon ground cinnamon, ⅛ teaspoon allspice, ⅛ teaspoon ground ginger, one pinch ground nutmeg. Add the celery seed to a coffee or spice grinder and grind until a powder. Add the remaining spices and grind a few times until blended.

Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days.
