Pesto Lasagna
This is a great lasagna for summer. It contains no meat and there is no tomato sauce. It makes use of that great summer basil and it can either be a side dish to grilled meats or a main dish.
If you want to save some cooking time, you can use no-boil lasagna noodles. Keep in mind, though, that these noodles require a lot of liquid or sauce in order for them to cook properly. They absorb a lot. So if you use these instead of regular cooked lasagna noodles, you have to make sure each layer is covered in plenty of sauce.
