1/2 cup breadcrumbs
1 cup marinara sauce
1 cup ricotta
4 ounces fresh mozzarella
Preheat the oven to 350. Peel zucchini, then slice it lengthwise into 1/4-inch pieces. Coat zucchini in breadcrumbs (make sure zucchini is moist enough; run pieces under cold water if necessary). In a medium skillet, add either a splash of oil, cooking spray, or butter — whatever you have. Cook zucchini in skillet on medium-low until breadcrumbs are golden brown, about 2 minutes on each side.
In an oven-safe dish, Add half of marinara. Then, add a spoonful of ricotta to the end of each zucchini slice, and roll up. Place zucchini in dish, then top each piece with fresh mozzarella and remaining marinara. Bake 20 minutes.
