Ingredients
Mushrooms and Marinade
- 1 pound portobello mushrooms
- 1 tablespoon oil (divided)
- 1 teaspoon vegan Worcestershire sauce
- 1 teaspoon salt
- 1 teaspoon black pepper
Vegetables
- 1 medium green bell pepper, seeded and sliced
- 1 medium red bell pepper, seeded and sliced
- 1 medium onion, peeled and thinly sliced
Sandwiches
- 4 sandwich rolls
- 2 cups vegan mozzarella shreds
Instructions
- Preheat the broiler: Set your oven to broil to get it ready for toasting the sandwiches later.
- Prepare and marinate mushrooms: Slice the portobello mushrooms into ¼-inch thick pieces. In a large bowl, toss the mushroom slices with 1 tablespoon of oil, vegan Worcestershire sauce, salt, and black pepper to evenly coat the mushrooms with flavor.
- Sauté mushrooms: Heat a medium sauté pan over medium-high heat and cook the marinated mushrooms until they are tender, about 5-7 minutes. Once cooked, remove the mushrooms from the pan and set aside.
- Sauté peppers and onions: Add the remaining tablespoon of oil to the same pan. Sauté the sliced green and red bell peppers along with the onions until the onions are golden and the peppers are tender, approximately 8 minutes. Then, add the cooked mushrooms back into the pan and stir everything together to combine the flavors.
- Assemble sandwiches: Spoon the mushroom and pepper mixture evenly into the sandwich rolls. Top each filled roll with about ½ cup of vegan mozzarella shreds.
- Broil to finish: Place the assembled sandwiches under the preheated broiler. Cook for about 4–5 minutes until the vegan cheese is melted and the bread is toasted to your liking. Watch closely to avoid burning.
Notes
- Use sandwich rolls sturdy enough to hold the filling without falling apart, such as hoagie rolls or sub buns.
- For extra flavor, consider adding garlic powder or smoked paprika to the mushroom marinade.
- If vegan Worcestershire sauce is unavailable, substitute with soy sauce or tamari for a similar umami taste.
- To make it gluten-free, use gluten-free sandwich rolls.
- Keep an eye on the sandwiches while broiling, as vegan cheese melts quickly and can burn if left unattended.
