Beef and Zucchini Casserole

Susan Feliciano


I call this "Jeanie's Beef and Zucchini Casserole", because it came from one of our church cookbooks and had her name on it. I haven't changed it too much - just the topping.
High in protein, low in carbohydrates, this has a great Italian flavor and goes together in a cinch. One serving has less than 200 calories and only 6.5 grams fat. A good way to use up all that zucchini that collects in the garden during the summer months. Good served with Risotto as a side dish.
