Are there any cheap meals I can make from condiment packages?

I have a ton of condiment packages, and I can't help but wonder if I can make meals out of them with little extra cost... Ketchup, mustard, mayo, picante sauce. I'm thinking Egg salad sandwiches with the mayo, just need a carton of eggs (Which I can get free from Target), relish, and bread. Just seeing if there are any other ideas out there...
