Believe me, we're there. I don't have a lot of ideas, but one that I use to cut down on grocery bills is a) to generally eat more vegetarian meals (pasta, beans, rice, tofu, eggs are all a lot cheaper than meat), and b) when we do eat meat, add veggies to stretch it out. For example, we had BBQ chicken for dinner last night, but I bought chicken tenders, grilled them and then shredded them. Then I cooked up some shredded carrot, onion and peppers and mixed in the chicken and BBQ sauce. It made 1 package of chicken tenders serve my husband and I, as well as our two kids (who eat about one each), with enough leftovers for a generous lunch today. Buying three whole chicken breasts would have been more expensive, and there wouldn't have been any leftovers. You can do the same things with hamburger, etc. Veggies are cheaper than meat, and I figure this way it's healthier too!
