Meatball and cauliflower pasta bake

This has to be one of the easiest things to chuck together, but it's tasty and relatively good for you.  Boil penne and cauliflower florets in salted water for about 9 minutes.  Mix 2 tins of chopped tomatoes with some squished garlic, salt and plenty of black pepper (you could cook this first, you could add other veg etc to make a more complex sauce, and/or chili to heat it up a bit, but this works).  Tip meatballs, drained pasta and cauliflower into oven proof dish, stir in tomato sauce.  Grate cheese on top.  In the oven for 20-30 minutes.  Scoff.  I wasn't sure if victim would like this, and we have been a bit pasta'd out recently - but the declaration was "tasty!".
