This is so incredibly easy, it's crazy. Place pasta, tomatoes, onion, garlic, red pepper flakes, salt and pepper, basil and onions in a straight side skillet. Add water or stock and olive oil. Bring to a boil over high heat. Using tongs stir and move pasta around pan as it boils. Cook for additional 9 minutes until pasta is al dente and liquid is reduced. Taste for seasoning. Garnish with basil and serve immediately with lots of parmesan cheese.
