Heat the oil in a large skillet. Add the broccoli, onion and bell pepper. Stir and sauté until it’s just beginning to soften. Add the turkey, garlic, and herbs and seasonings for the filling. Mix and cook until heated through. Add the 1 1/2 cups ricotta and stir until it melts into the filling. You can use a tablespoon of water or broth if you need to thin it a bit.
