Do you like tuna or other fish or meat? You could do it without meat if you want.

Do you have a sandwich press?

I puree 2 eggs, a can of tuna and a cup of rice (other grain would be fine). Dump it on the sandwich press and put some toppings on if I want (olives and tomato). (Salt, pepper and a bit of dill and cumin for a bit of lemon taste because I think ds might react to lemon.)

My kid who hates tuna actually asked for a 'tuna pizza pocket' for dinner.

You never know what'll hit them just right.

Sorry about the 2 eggs... you should be able to substitute some flax and water for them.
