We have chicken or pasta a least once a week. Chicken gets a little old, especially the way my mom makes it, but I never get tired of pasta. :p
Oh, and taquitos. I lived off of taquitos for two weeks once. I still like them a lot, but I eat them way too much when we have them. XD
EDIT: Oh, and when I'm at school, pizza. Pizza is pretty much the school's official "we don't feel like cooking so let's sling some easy-to-make crap together" meal. We have it at least once a week, and the school makes three different varieties of it. One is like you get from restaurants only sickeningly greasy, one is like a crust-bowl with way too much sauce and some cheese on top, and the last is pizza bread that's actually good. But I get so tired of pizza that some days I'd rather go without lunch than eat it again. :(
