This is a first for me: Stuffed Portobello Mushrooms. This is such a versatile dish. You can really add or eliminate whatever you want. Here's the laundry list of things I used (I chopped or diced every ingredient and mixed together):
The stems of the mushrooms
Yellow bell pepper
Fava (or any type) beans for added protein
Feta, parmesan & mozzarella cheeses
Basil, pepper & cumin
Baked at 400* for about 30-40 minutes.
