Food Rut

After a couple months of denying it, I finally have to admit that I have been in a food rut for a while now.  This summer when I was living on my own I cooked all my own food and consistently made/snacked on the same foods.  Now that I'm living at home, I am more limited in what I am eating (I go for whatever is in the kitchen so save money) but am still sticking to the same foods.  I have a really busy/strange schedule this semester that requires a lot of snacks, meals at unusual times and early dinners.  I think its time to think of this as an opportunity to start eating more creatively. 

Any foods you're falling into a rut with (my snacks are awful!)?  Any new food ideas I should know about?
