Here's one of my favorite things to throw together for dinner. It is very quick to make. If you have peeled shrimp, it would be even faster.
I don't have a recipe I follow, so here's what I do: In a large skillet, saute a lot of chopped garlic(I use about 5 large cloves) in a couple of tablespoons olive oil. Cook at low temperature until soft. Add a large pinch of red pepper flakes, and deglaze the pan with some white wine(maybe 1/2 cup). Add your shrimp, and cook until done. In the meantime, put on a lg pan of water to boil and cook spaghetti until al dente. Drain, and add to pan of shrimp. Toss to coat. If it's a little dry, add a some more olive oil.
