Ingredients
- 3 tablespoons olive oil
- 32 oz mushrooms cremini, Portobello, or a mix, sliced
- 1 large onion thinly sliced
- 2 garlic cloves sliced
- 2 tablespoons soy sauce
- Pinch of salt
- Freshly ground black pepper to taste
- For the sandwich:
- 4 pieces French bread or baguette
- 4 slices cheese slices smoked or your favorite variety
Instructions
- In a large frying pan, heat the olive oil over medium heat. Add the mushrooms, onion, and garlic. Sauté for 5–7 minutes, or until the onions are soft and the mushrooms are fully cooked.
- Stir in the soy sauce, a pinch of salt, and black pepper to taste. Continue cooking until most of the liquid has evaporated and the mixture is golden and flavorful.
- Slice the French bread down the middle without cutting all the way through. Stuff each one with the mushroom-onion mixture and top with a slice of vegan cheese.
- Place the sandwiches in the oven or toaster oven for a few minutes, just until the cheese melts. Serve hot and enjoy immediately.
Notes
Best eaten right after assembling to avoid soggy bread.
Feel free to customize with mustard, vegan mayo, pickles, or avocado.
You can also grill the sandwich or use sandwich bread and toast it on a griddle.
