Oyster mushrooms have been used in traditional Chinese medicine as early as 3,000 years ago as tonics for the immune system. Today they still enhance your immune system as well as improve its regulation. They contain ergothioneine, a unique antioxidant exclusive to mushrooms, to help protect your body cells.

3 cups oyster mushrooms, sliced

1-2 tbsp olive oil

1-2 tbsp rice vinegar

1 ½ tbsp ground flaxseeds + 4 tbsp water (or use 2 egg whites)

1/3 cup cornmeal

1/3 cup panko breadcrumbs

1 tsp Old Bay seasoning or Cajun seasoning

¼ tsp cayenne

sea salt and ground pepper, to taste

for the sandwiches:

4 pieces of baguette

sauces: spicy mustard, mayonnaise, veganaise

a few handfuls of lettuce

sliced tomatoes



Use a damp towel to gently clean the mushrooms. Cut into smaller pieces and place in a medium sized bowl. Drizzle with olive oil, rice vinegar and sprinkle with a pinch of salt. Gently toss and set aside to marinate.

Preheat the oven to 230 degrees C and line a baking sheet with parchment paper.

In a small bowl combine the ground flaxseed and water OR use 2 egg whites. In a second small bowl combine the cornmeal, panko, Cajun seasoning, cayenne, and a few pinches of salt and pepper.

Bread the mushrooms by dipping each into the flax mixture and then the breading mixture. Repeat for all the mushrooms. Bake for 10-12 minutes until golden brown and crisp on the edges.

Assemble sandwiches by filling buns with chosen sauces, lettuce, tomato slices, pickles and cooked mushrooms. Yum!
