Step 1: Boil a pan of water (enough to cover however much pasta you want – don’t use too much pasta otherwise there’ll not be enough sauce) and cook your pasta while you prepare everything else.
Step 3: cut the sausages into chunks (not too big) and fry them until browned.
Step 5: add the onion and peppers (plus garlic and any other veg, if you’re using it) to the pan and cook until they are starting to soften.
Step 7: pour in the tin of chopped tomatoes and leave to cook for 5 minutes.
Step 9: add your mushrooms. Season to taste with mixed herbs (and chilli, if you’re using it).
Step 11: drain your pasta and mix your it with your sauce. If your sauce isn’t covering all of the pasta, (or if you’d like it a bit more tomatoey) add some passata until there’s enough.
Step 13: leave it for a few minutes, until your extra passata heats up, then serve!
