Hang in there. I've been there too many times. When the kids were home. I would make a beef rice and chicken rice where I would buy cube steak, season it and brown it. Then cut it up in small pieces. If I could get beef broth GREAT if I couldn't then it was just flour and water to thicken it all together. The same thing with the chicken except it was cream of chicken soup. I could get about 3 days out of each batch. We'd have ramen noodles or cereal in between. Of course the kids at their fill and I made due with what I could.
RE: A bag of rice is a wonderful thing.
