This recipe takes way longer than it states, but makes lots of leftovers, so it's worth the time. I used canned Hunt's sauce instead of making my own, and added grated Parmesan cheese. The recipe also doesn't state the temperature or time to bake, but the pasta box did. I baked at 400 for about 20 minutes (it says 30, but it was done sooner). Between the time it takes to start boiling the water and thawing the spinach, and the time to boil pasta, fill pasta, bake, cool, and serve, it's at least an hour to table.
