Best canned food? (Small cans)

Hi there! My baby likes wet food but she won’t eat it after it’s been sitting in the fridge, she only likes it fresh out of the can/packet. We tried just food but she only eats the first serving. And believe me, we’ve tried everything from reheating to adding hot water or broth… just nothing after the first serving. So I’d like to find her a good food that comes in the single serving packets or cans. Any ideas?

Thanks!
