One great thing about this lasagna is that the noodles don’t need to be pre-boiled. The dish has a lot of liquid (in the form of sauce) and goes into the oven covered, so the noodles get cooked perfectly as the lasagna bakes. Add a green salad, and serve some Chianti or California red Zinfandel with the main course.
Makes 6 to 8 servings.
