1 tsp dried basil
1/2 tsp hot red pepper flakes
Salt to taste
Prepare pasta according to package directions. While pasta is cooking, combine remaining ingredients in a 2-quart saucepan and heat to boiling. Reduce heat and simmer until the liquid is reduced by half, approximately 10-20 minutes. In a food processor or blender, puree small quantities of the sauce to desired consistency, using 3 to 4 quick on-off motions for a chunky sauce, longer for a smoother sauce. When pasta is done, drain. Pour sauce over pasta and serve immediately.
