In a 450 degree oven, roast the tomatoes, garlic, bread, nuts and pepper on a baking sheet for 15 minutes. Transfer to a food processor pulse to roughly chop. Add the vinegar, oil, paprika, and salt and pulse until well combined.
Cook spaghetti in a large pot of boiling salted water until al dente. Drain, reserving some of the pasta cooking water. Toss cooked spaghetti with desired amount of Romesco Sauce, thinning as desired with the pasta cooking water. Serve immediately with grated cheese on top.
