This was my mom's recipe that I "enhanced" a little bit (by adding lots of cheese!) Everytime we have company, this is my go-to meal. Everyone raves about it, and it's not that hard. You can prep it a day ahead and keep it in the fridge, or even freeze it! Add a salad and some garlic bread...wow!
If you use the No-Boil Lasagna Noodles, you will want to add all of the liquid from the diced tomatoes to make sure there is enough liquid to cook the noodles. If you boil the noodles ahead of time, you can use less liquid so the lasagna isn't runny in the end.
