Probably the least expensive quick lunch at MK is Casey's Corner. Our vote for the best MK counter service is Columbia Harbour House.
At MGM, Toy Story Pizza Planet is our favorite, although we aren't big fans of any MGM counter service restaurants. The combination meals at Pizza Planet are a pretty good deal. A personal pizza, side salad, and drink are included.

How many are travelling? If you're by yourself then cheapest is cheapest per menu but if you can share with others in your travelling party then the cheapest per person is a very different story. Quick is mostly about timing - avoid noon-1. Our family's strategy is to split at Cosmic Rays (MK) or Pizza Planet(Studios) at 11 a.m. then get an afternoon snack around 2 - either from a cart or split another meal at CS. I check the menus on allearsnet.com to determine where we can get the best value for what our family wants.
My DS's love Pecos Bills in MK, but my favorite is Cosmic Ray's!! The burgers are fantastic!! On our first day there I had one for breakfast, I couldn't wait!
