Method
Preparation
- Heat a skillet over medium-high heat with a small splash of oil. Add the sliced onions first and cook until they begin to soften.
- Add the bell peppers and mushrooms, stirring occasionally until everything is browned and tender.
- Lower the heat and pour in the vegan cheese sauce. Stir to coat all the vegetables evenly and allow the sauce to warm through.
- Split the rolls and, if desired, toast briefly to add structure. Pile the cheesy vegetable mix into each roll.
- Serve immediately while the sauce is warm and melty, optionally adding toppings like pickled jalapeños or fresh parsley.
