Ed's Modified But Still Extra Easy Meat Lasagna

I find it a bit surprising that I have not yet posted a lasagna recipe, but that might be a result of never learning how to make one from my dad. I still need to learn his recipe. Until then, I've found an "Extra Easy Lasagna" recipe from myrecipes.com, and, of course, modified it.
You expected that, I'm sure.
Here's my version:
Ed's Modified But Still Extra Easy Meat Lasagna Recipe

24 oz. Sausage
2-24oz Cans or Jars Spaghetti Sauce (see note)
9 Uncooked Lasagna Noodles (regular or whole wheat)
1-15oz Container Ricotta Cheese
3 Cups grated Mozzarella or Italian Cheese
1/3 Cup Hot Water

Crumble and brown sausage in a large skillet while pre-heating the oven to 375 degrees. Drain off the fat, and stir in both containers of spaghetti sauce. Cover the bottom of a large casserole dish with about a quarter of the meat and sauce mixture, then layer three of the uncooked noodles on it. Spread about a quarter of the Ricotta cheese thinly on top of the noodles, and then layer about a half-cup of shredded cheese on it. Repeat layering with meat sauce, noodles, and cheeses, twice, retaining at least a cup of shredded cheese for later. Pour the hot water around the edge of the noodles. Tightly cover the dish with two layers of aluminum foil. Place the dish in the preheated oven and bake for 1 hour to 1 hour 10 minutes (until hot in the center). Uncover the Lasagna, cover with the remaining shredded cheese, and return to the oven for 10 minutes. Remove and allow to cool for 10 minutes before serving.

Note on Spaghetti Sauce selection: I recommend using two different sauces in this recipe, but be careful about which. Four cheese may clash with the Ricotta, meat may clash with the sausage. Traditional should go fine, as will tomato and basil, chunky garden style, and many others. You may even want to try this recipe with some kinds of Alfredo sauce and let me know how it comes out!
