Heat salted water in a medium pot to boil. While waiting for the water to boil, saute the spinach in a skillet with the olive oil, until wilted.
When the water boils, add the ravioli. Reserve 1/2 cup pasta water. Remove the ravioli when it's cooked and rises to the top. (Taste one for doneness first.)
Place the cooked ravioli in the sauce pan with the spinach. Add the two tablespoons of pesto, and add enough of the pasta water to make a creamy sauce. Mix thoroughly and serve with fresh grated cheese.
