Shrimp Fra Diavolo with Vermicelli

In a large frying pan, heat the oil over medium-low heat. Add the onion and cook, stirring occasionally, until translucent, about 5 minutes. Add the garlic and sauté 30 seconds longer. Stir in the tomatoes, red-pepper flakes, water, parsley, and salt. Reduce the heat to low. Cover and simmer 10 minutes. Add the shrimp. Cover and cook just until the shrimp are pink, about 4 minutes.

Cook the vermicelli in a large pot of boiling salted water until just done, about 9 minutes. Drain the pasta and toss with the tomato sauce and shrimp.
