I would use fresh spinach, fresh tomatoes, and fresh
ground beef, turkey or sausage. Sometimes I drop by our wonderful Italian Restaurant and pick up a pint or quart of their sauce and use that. It's so easy and so cheap - I usually buy my cheese from SAMS and I shred it as I'm waiting for the meat to brown. My family loves it and if you mix it up the night before and put it in the oven the next day - it smells so good and tastes even better. It is FRESH, EASY TO FIX and CHEAP. A salad with this goes well (fruit) or (Vegetable) and Bread Sticks. This is West Virginia Style.
I would not use the above recipe for my kids.
