Dd (almost 17 months) only wants finger foods for lunch. She is happily spoon fed breakfast and dinner but refuses at lunch 
She won't eat sandwiches(but loves toast), cheese or pasta and only seems to like white fish.
I'd like to make some things and keep them in the freezer.
I can only think of chicken nuggets, fish fingers/fish cakes or omelette/frittata.
Any other ideas would be greatly appreciated!
