Quick easy meals for 16 month old toddlers.?

Question

I am a live in nanny for 16 month old triplets. I need some help with quick meal ideas. Now I know what fruit they like that's not a problem. I need to find something for the main part or the meal and the vegetables (I find giving these first works best)

I am looking for stuff they will eat up fast and enjoy.

I am looking for something I can make and then freez or save for times when we are busy.

I am looking for mess free ideas

I am looking for messy ideas

I am looking for fun food.

They seem to not like sandwiches or sandwich meat.

They like tofu.

We have an allergy to milk.

They also can be no nuts in any of the food as there is an allergy to nuts in the family.

Thanx so much!
