Erm... most of them!
Barbecued anything and salad....
if you can find time to make a big batch of bolognaise sauce, freeze it in tubs and defrost as required, for an easy no-think pasta meal (DD eats this for dinner 90% of the time!)
Pasta is easy to do with a quick creamy sauce - I like to fry some bacon or ham, throw in some leeks, sweat down for a few minutes then add cream and gorgonzola cheese or just plain grated cheddar is also fine - the sauce takes about as long to make as the pasta does to cook. I do these for DD as the Bear is on low carb so no pasta dinners for us.
Other quick meals - lemon and basil chicken - throw a jointed chicken in a roasting dish, season with salt and pepper, pour in a glug of olive oil, the juice of a lemon, the lemon shells and a couple of whole cloves of garlic, cook at 180-200 for 45 mins to 1 hour (depending on your oven) pull out and chuck on some torn basil leaves, cook for another 15 mins then put on the stove top and pour in a glug of white wine, let it bubble over the heat for about 2 mins and serve with nice fresh salad leaves (no dressing required as the sauce is lovely).
