ok easy one i do when i cant really be bothered

one med onion white chopped
two garlic cloves (pending on preferance)
one pack of bacon chopped
2 tins of chopped tommies or plum chopped up (cheaper can )
good handfull of mushrooms chopped

fry all cept tommies in olive oil if you have it if not just normal oil, till bacon is crispy add tomatoes lower heat and simmer til reduced approx 20 mins add basil (fresh is better but dried is fine)
(if you have any whole grain mustard in the cupboard half a spoon of that is nice in it )
season to taste
later when you want to eat boil your pasta drain add you reheated better flavoured sauce

n.b. when i cook this it takes the time to boil pasta so 20 mins really, simmer it down to reduce the watery look, leave aside, cover, boil pasta reheat sauce as needed, mix together, sprinkle cheese and basil on top done
