So...starches-do you only need to limit them if you are trying to lose weight?

My question really is about /for my children. None of them are overweight, all on primal but they seem to be hungry a lot!
They eat fruit, nuts, seeds and olives for snacks.

Can you give me some good examples of dinners for kids please?!

Last night we had beef chilli and sweet potato chips, they all loved it and the littlest slept through the night WOO HOO!
But, I can't give them sweet potato everyday... So ideas please
Thanks all, don't want to damage their growth etc because I'm unimformed. I can't seem to find much online about kids and paleo apart from 'baked goods'. Which I think are fine sometimes, but not something I want to use to fill them up with everyday.
