Clean the portobello mushroom caps with a damp paper towel. Remove the stems and use a spoon to gently scrape out the gills. Slice the mushrooms into thick strips.
Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add the mushroom slices and cook for 5-6 minutes, stirring occasionally, until they are browned and tender. Transfer the mushrooms to a plate and set aside.
In the same skillet, add 1 tablespoon of olive oil and 2 tablespoons of butter. Once the butter is melted, add the sliced onion and green bell pepper. Cook for 8-10 minutes, stirring occasionally, until the vegetables are softened and lightly caramelized.
Add the minced garlic to the skillet and cook for 1 minute, until fragrant.
Return the cooked mushrooms to the skillet. Season the mixture with salt and black pepper, stirring everything to combine. Remove from heat.
Preheat the broiler. Slice the sub rolls in half lengthwise and place them on a baking sheet. Toast the rolls under the broiler for 1-2 minutes, watching carefully to avoid burning.
Spread mayonnaise (if using) on the toasted halves of each roll.
Divide the mushroom mixture evenly among the rolls. Top each sandwich with a slice of provolone cheese. Place the sandwiches back under the broiler for 1-2 minutes, until the cheese has melted.
Serve the sandwiches warm and enjoy!
