If you absolutely HAVE to quit quilting to feed the family then cook LOTS and LOTS. Freeze the leftovers in smaller portions so that they can heat it up themselves the next time they're hungry.
Seriously though, I do try to make enough for at least two meals. I also purchase the biggest package of 93/7 hamburger that I can at Walmart, bring it home, cook it, drain and cool it, then bag it in quart freezer bags. When I want to make tacos, spagetti, hamburger casserole, chili or anything else needing hamburger I just grab and bag and dump it in.
