  1. Preheat oven to 350 degrees F (175 degrees C). Lightly oil a 8x8-inch casserole dish with cooking spray and set aside.
  2. Heat olive oil in a saucepan over medium-high heat. Stir in green pepper, garlic, and green onions; cook until the pepper softens, about 3 minutes. Pour in marinara sauce and simmer 5 to 7 minutes, stirring occasionally.
  3. Mix together fontina and provolone in a bowl. Spread a thin layer of sauce over the bottom of the prepared baking dish. Arrange 1/3 of the polenta slices in the dish, top with 1/3 the fontina and provolone mixture. Spread a thin layer of sauce over cheese. Repeat layers twice. Top casserole with Parmesan cheese.
  4. Bake in preheated oven until cheese is bubbly and golden brown, about 25 minutes.

Very good. Added mushrooms. Used red pepper, yellow onion, Italian blend cheese. What I had on hand...and needed to use. Had to add a bit more than 14 ounces sauce...probably because of the adde...

I'm so bummed! I did not pay attention to my jarred sauce and added 26 ounces instead of 14. It was way too soupy. Will have to try again. I swapped yellow onion instead of green onion and red ...

Simple and delicious. Instead of sauteeing peppers and onions, I just stirred my favorite spices into the sauce and used homemade polenta. We all enjoyed this!
