Ugh, meal planning

I can't believe it's April already this week!! This year is flying by! Right now, I'm on spring break, Jeff's basically in between his jobs, and things are tight. Because of that, I have to get creative with meal planning (I hate meal planning in general, so this is about a thousand times worse!), using the cheapest ingredients for meals, and hopefully keeping them simple too. I think if I buy a bag of potatoes and some chicken (in addition to what is already in the house), we at least have thirteen dinners. Combine that with being gone for a few days and Easter, and we make it until a few days before I go back to work. Now, for lunches... If anyone has suggestions for simple meals (lunch or dinner, since some of my dinners can be used as lunches too) that can usually be made from what's in the house (and NO ground beef), or meals that don't need a lot of different ingredients (or expensive ones), pass them along please!
