Mushroom Parmesan

olive oil
4-6 portobello mushrooms
1/2 tsp. salt
1/4 tsp. black pepper
marinara sauce
1/2 cup shredded mozzarella cheese
1/4 cup grated Parmesan
2 tablespoons butter, cut into small pieces.

Place a grill pan over medium-high heat. (Grease grill pan before using)
Drizzle some olive oil over both sides of the mushrooms. Sprinkle the mushrooms with salt & pepper. Grill the mushrooms until they are heated through and tender, about 5 minutes per side.

Preheat oven to 400 degrees

Spread some marinara sauce on the bottom of a 9 x 13 in baking dish. Place the grilled mushrooms on top of the marinara sauce and top with more marinara sauce. Sprinkle with the cheeses and top with the butter pieces. Bake until the cheese melts and the top is golden, about 15 minutes.
