Toad in the hole - you can use the same batter for both and then do one dish with normal sausages for the dc and one with veggie sausages for you (if they won't eat veggie sausages)
Macaroni/cauliflower cheese
Falafel with wedges
Baked potato with spicy beans (either make your own or Heinz do some good ones)
Frittata
Egg fried rice
Pasta and pesto
What sorts of things are you having at the moment?
