pasta cooked in one pot

sometimes when i go shopping and i see semi preprepared meals like dinner winner and wonder what they're like, but never have the guts to try them. instead, i use the same concept they use and sometimes cook my pasta like this. i'm sure it wouldn't win any brownie points with italians, but it ain't half bad.

375 grams lean mince
2 tablespoons olive oil
200 grams sliced mushrooms
1 capsicum, chopped
1 onion, chopped
4 cloves garlic, minced
a few sprigs parsley, basil, oregano, chopped roughly
750 mL tomato basil pasta sauce
salt and pepper
500 grams pasta
parmesan cheese to serve

heat the olive oil in a large deep saucepan and add the onions and garlic and cook over medium heat until the onions have softened. add the beef, breaking it up with a spoon, and cook until no longer pink. add the mushrooms, capsicum, herbs and salt and pepper; cook, stirring occasionally, for about 10 minutes.
add pasta sauce, 3 cups water (this depends on the pasta you're using - use good judgement and adjust accordingly; also, i like to replace some of the water with wine) and bring to the boil. add pasta; reduce heat, cover and simmer, stirring occasionally, until pasta is tender but firm, about 12 minutes. check for seasoning and adjust, if necessary.
serve sprinkled with parmesan cheese.
