What are some EASY, inexpensive meal ideas to feed a large family?

Chicken enchiladas are easy and stretch.Flour tortillas,chopped onions,chopped up chicken meat(or beef)and 2 cans green enchilada sauce.Put your onions,meat and 1 can of sauce to heat thru.Take a slotted spoon and scoop out meat,roll inside a tortilla.line them up in a large pan(spray with Pam so no sticking).Pour all sauce in over the enchiladas and top with cheese and bake for 30 mins at 350.Serve beans and rice or just a green salad....Hope this helps.I make 2 per person for my gang....
