I need meal ideas for my son with food allergies?

He is 2 years old severely allergic to milk and has mild allergies to nut and egg. He can eat some products with egg in it such as egg noodles. The only vegetable he will eat is green beans and he eats his fruits fine. I feel bad because he usually has to eat the same stuff, (cereal,sloppy joe, lunch meat, chicken nuggets fish sticks and noodles are some common meals). What are some ideas for meals for him to eat.
