Sometimes when I'm given a really good home cooked meal, I'll end it with saying

Wow, that was a great meal, thank you. I could eat that all over again!

This sends the compliment to your hosts and also gives them a reason to ask if you wanted any more (without you having to ask directly).

If I'm hungry, I'd gladly take a little more if offered. If none is offered, I'd be happy that I've complimented my hosts regardless.
