Ingredients
- 8 oz Portobello mushrooms
- 1 medium Green bell pepper
- 1 medium Red bell pepper
- 1 medium Yellow onion
- 2 tbsp Olive oil
- 1 tsp Garlic powder
- 0.5 tsp Salt
- 0.5 tsp Black pepper
- 4 large Hoagie rolls
- 8 slices Provolone cheese
- 0.25 cup Mayonnaise

Instructions
Clean the Portobello mushrooms by wiping them with a damp cloth, then slice them into thin strips.
Cut the green bell pepper, red bell pepper, and yellow onion into thin slices.
In a large skillet, heat olive oil over medium heat.
Add the sliced onions to the skillet and sauté for about 3 minutes until they begin to soften.
Add the sliced mushrooms and bell peppers to the skillet and cook for an additional 7 minutes or until the vegetables are tender.
Sprinkle the garlic powder, salt, and black pepper over the vegetables and stir well to combine.
Preheat the oven to 350°F (175°C).
In a small bowl, mix the mayonnaise and Dijon mustard together.
Slice the hoagie rolls open, but not all the way through, and spread the mayonnaise mixture on the inside of each roll.
Divide the vegetable mixture evenly among the hoagie rolls.
Top each sandwich with two slices of provolone cheese.
Place the sandwiches on a baking sheet and bake in the preheated oven for 5 minutes or until the cheese is melted and bubbly.
Remove from the oven and serve hot.
