Preheat the oven to 350° F. Wash and dry the spinach. Heat the olive oil in a pan, add the spinach and season with salt and
pepper to taste. Sauté until the spinach is cooked, about 5 minutes. Drain the spinach, roughly chop it, then squeeze out any
remaining moisture. (You can also use a generous cup of frozen leaf spinach, defrosted and drained.)
