Lightened up Healthy Green Bean Casserole made with fresh green beans, mushrooms, and a crispy parmesan topping! This crowd pleasing Thanksgiving classic is creamy and flavorful yet contains no canned soup.
Preheat oven to 425 degrees F. Place bell peppers in a large 9×13 baking dish, drizzle with 2 tablespoon olive oil and toss with a spoon to coat evenly.
Sprinkle with salt and pepper, toss again and flatten into a single layer as much as possible. Bake for 25-30 minutes or until peppers are soft when pierced with a knife and have some blistered spots.
