Great--cooked inside or out.
What You'll Need:
4 portabella mushrooms caps, stems removed
marinara (I love the red sauce from the Fixate Cookbook--make in big batches!)
1 white navy beans, drained and rinsed
1 small box/bag spinach
shredded Parmesan, right from the block
salt and pepper
Preheat oven to 375*
Heat oil in a large frying pan. Cook mushroom caps, flipping as needed, until tender--about 8 minutes. (You could grill them, too!)
Then, wilt spinach leaves in warm skillet.
Arrange caps on a baking dish. Top with red sauce, white beans, cooked spinach and cheese, S&P. Bake for 5-7 minutes, or until cheese is ooey-gooey.
Serves 2. You can fill these bad boys with whatever your heart desires.
