These were super easy to make. You will need:
2 or 3 large portabella mushrooms per person, stems removed and wiped clean
1/2 c of your favorite tomato sauce, preferably home made, per person
a little olive oil
Your favorite toppings, I used peppers and vidalia onions
1 slice of mozzeralla cheese for each mushroom
parmesean or romano cheese for grating
pinch of crush red pepper flakes
Fresh basil, finely sliced
Turn your oven onto 400 degrees to preheat.
In a large nonstick skillet, heat a small amount of olive oil. Put in as many mushroom as will fit in the pan. Cook the mushrooms flipping a couple of times until they are softened. If you don't cook them ahead of time, they'll still be raw when you go to eat them, blech! Continue cooking your mushrooms until you have them all precooked.
Place the mushrooms in a baking dish that is large enough to hold them all. It needs to be at least 1" deep since there will be lots of juice, not a bad thing!
Top each mushroom with some of the tomato sauce, add a pinch of salt and crushed red pepper. Add a few threads of the sliced basil. Cover each mushroom with a slice of mozzerella. Top with your favorite pizza fixins. Add some parmesean if you like. Pop in the oven for 15 minutes or so, or until they are nicely browned.
They don't make a crisp pizza, but the flavor is incredible.
