I have a lemon linguine recipe in my repertoire (you might have seen it before here) that is simple and delicious. Tonight I made a version of lemon linguine with shrimp. This go around, while the pasta was cooking, I sauteed some shrimp in olive oil and butter with some lemon juice, chives and red pepper flakes. Once the pasta was just shy of al dente, I drained the pasta while reserving some of the pasta water. I added the cooked pasta to the pan with the sauteed shrimp, added a wee bit more butter and some spinach with the reserved pasta water, covered the pan and let it simmer for just a couple of minutes.
If you don't have or don't like shrimp, you could make this same recipe with chicken.
I served it up with a fresh tomato and basil salad.
