What is the healthiest canned cat food you can get from a regular grocery store?



I know you can get great gourmet ones from a pet store, but if I were to just walk in Publix or any grocery store, what kind of cat food is the best? I have EVO for my cat, but the other day it was too late to go to the pet store, so I went to the grocery store and got her Fancy Feast and she LOVED it... is it the healthiest best one for a cat to eat?
