I have many fond memories of making this several times a week whilst I was in Uni!
Cut up bacon rashers into strips (around 2 rashers per person). Fry until beginning to brown.
Put the pasta on to boil- I recommend Fusilli (twists).
Add 1 chopped up red onion, 1 clove garlic.
Add 2 chopped red peppers and a handful of mushrooms.
Add a tin of tomatoes.
Season with black pepper, oregano and basil (fresh if poss).
Serve pasta with the sauce poured over it.
