Cook the spaghetti in salted water. Let about 4 tablespoons of olive oil get hot in the wok. Chop the bacon (vegetarians leave it out) and garlic and fry in the oil. Then deglaze with some of the pasta water. Add a little parsley. Season with a little salt, pepper and possibly chili powder or dried pods. Add the pasta. Pour in a little more olive oil and knead well. Let it flow briefly.
