Roast the peppers in the oven for ten minutes in a little bit of olive oil.
After 5 minutes add the tomatoes and cook until they are cooked and softened.
Let them cool for 5 minutes and out in the blender with the garlic and a tbs of olive oil and blend. It should be a bright red/orange smooth sauce (add some water if a bit rough).
Cook your pasta in salted water and heat up your sauce in a pan on a low heat and season.
Add your cooked pasta to the pan (and a spoonful of pasta water if needed) and toss until covered in the lovely sauce.
You can add nutritional yeast for a cheesy flavour if u wish
