Ideas for a broke mother of 2 ? Cheap meals, etc?

I have two children and are going through some financial problems right now, my husband just got a new job but he is in school for nine weeks with no pay until he can start making money again. I'm home with my children ( daycare costs more than I'll make working for 2 kids, & no, I cannot get any subsidy) anyways I'm mostly looking for cheap medl ideas but also nutritious ones, anyone have any meal ideas that can stretch through the week ? Or any other ideas for living on a very very low budget? Thanks
