Food recs?

My GP is SUPER picky. Seriously, she has hated nearly every food we've tried, both wet and dry, both the expensive stuff and the cheap stuff, large breed stuff and regular size, puppy food and adult food. She'll eat some "people" foods (cheese, eggs, meats) but hates a lot of commonly liked treats (peanut butter, fruits, veggies). Anybody have any suggestions for wet and/or dry foods your GPs like that won't break the bank? Her weight seems good but I want to make sure she's getting enough nutrition, because right now her nutrition primarily consists of the people foods she'll eat as well as dog treats (she \*loves\* dental greensticks and most other dog treats we've tried, but she can't subsist on treats alone).
