Method
Steak-style Veggie Filling
Heat pan
Place a large skillet or cast-iron pan over medium-high heat. Add 1 tablespoon olive oil and 1 tablespoon butter. Allow butter to melt and foam but not burn (about 30–45 seconds).
Add mushrooms and peppers
Add the mushrooms, sweet bell pepper, and hot peppers to the pan. Add the remaining 1 tablespoon olive oil. Stir to combine and spread into a single layer. Allow to sear without moving for 1–2 minutes to develop color, then continue to cook, stirring occasionally, until mushrooms have released moisture and everything is nicely browned and tender, about 6–8 more minutes.
Season and finish
Lower heat to medium. Add remaining salt, black pepper, and Worcestershire sauce if using. Stir and cook 1 more minute to incorporate flavors. Taste and adjust seasoning. If mixture seems too wet, cook another 1–2 minutes to evaporate excess liquid. Keep filling warm in the pan on the lowest heat setting while you prepare bread and cheese.
Cheese & Bread
Divide the warm veggie filling evenly between the two rolls, piling it onto the bottom halves. Arrange 2 slices of white American cheese over the hot filling on each sandwich so the cheese melts from the residual heat. If using an oven broiler, place assembled sandwiches on a baking sheet and broil 1–2 minutes until cheese is melted and edges of rolls are toasted—watch closely to avoid burning. Alternatively, cover the pan with a lid for 1–2 minutes to help cheese melt.
Fresh Toppings & Assembly
Spread mayonnaise (if using) thinly on the top half of each roll. Top the melted-cheese covered filling with shredded lettuce, tomato slices, and sliced black olives, dividing evenly between sandwiches.
If you prefer the fresh toppings chilled, refrigerate lettuce and tomato until assembly time to keep them crisp. Sprinkle a small pinch of red pepper flakes over the filling for extra heat, if desired.
Close the sandwiches, press gently, slice in half if desired, and serve immediately while the filling is warm and cheese is melty.
