Betsy's Awesome Vegetarian Sandwich

I first had this when i was working in a mall in the early 1990's. This is my version that i've been eating ever since.

Prepare the sandwich rolls by slathering mayonnaise on them.

Melt butter in large saute pan over med-high heat.

Saute green pepper and onion together , until starting to soften.

Add mushrooms , breaking the slices up into smaller pieces while doing so.

Saute this mixture for another couple minutes until mushrooms start to soften.

Now add the sliced olives.

Stir it all around a bit , until the olives are heated through.

Now divide it into 2 portions , each on one side of the pan.

Turn heat to low and put 1 slice of swiss cheese and 1 / 2 of a slice of provolone cheese over each portion.

Let melt and turn off heat.

Using a spatula , slide portions into their respective sandwich rolls.

Some may fall out so put it back in !.

Now add your preferred amount of lettuce and tomato and dig in !.
