I've been making stuffed portobellos for years in a similar fashion. The recipe changes every time based on what I have on hand. Last time I used about 3/4 cup leftover cooked basmati rice, sauteed summer squash, zucchini, tomato, onion, garlic, about 1/2 cup breadcrumbs, and 1/2 cup chedder cheese. I also like to add 1 beaten egg to help it all hold together. If you don't have time to marinate, drizzle the mushroom caps (stem side up) with a little balsamic (not too much, it can be overpowering) or soy sauce and bake for about 10 mins before topping with the stuffing.
