It's easy to cook, all the main ingredients are always in my store cupboard, and the children love it.
Cook some pasta until al dente.
Hunt around for any stray vegetables in your fridge or cupboard - any of the following are good: courgette, peppers, sweetcorn, olives, onions, mushrooms or tomatoes. If you prefer, fry them off a little.
Mix the al dente pasta, a tin of chopped tomatoes, a few herbs, a tin of tuna chunks and the vegetables. Top with grated cheese and bake in the oven for 15 or 20 minutes at 180 C.
As an alternative you can exchange the tuna for some fried off lardons or pancetta or chopped bacon, or cooked chicken.
