1.Preheat oven to 400 degrees, have a cookie sheet lined with foil ready and set aside.
2.Mist a round or square casserole dish (about 9 inches) with cooking spray. Toss the veggies, cut up meatballs and gravy in the casserole dish and gently mix together.
3.In a medium mixing bowl, stir the Bisquick, milk and egg together. It’s okay if the batter is a little lumpy. Try not to over mix but make sure all is combined. Pour over the meatballs and vegetables. Gently smooth around to make as even as possible. Place baking dish onto prepared baking sheet.
4.Bake for about 30 minutes or until you see bubbling and the crust is golden brown.
5.When you take out, let cool for only about 5 minutes on a cooling rack.With a large serving spoon, plate up and enjoy this hearty, delicious meal. I served this with a salad and fresh homemade raspberry iced tea, a favorite from the south. Also, a simple recipe.
