Donna, how about making a huge pot of spagetti Bolognaise sauce, it's really cheap - and you can freeze it in little containers, enough for one meal at a time. It's also easy, you just have to boil the spagetti.

Don't buy already grated Parmesan, get a good chunk of it and grate yourself - that will also go in the freezer. You can save a lot of money this way, and get better quality.

This is also quite cheap. Make a lot of meatballs, you can also freeze those. Have them with cold potato salad. The meatballs are a bit time consuming, but once they're done ....
