I've never tried to make one myself, but I'm guessing I'd suck at it.
Preheat oven to 350. Boil noodles(don't fully cook, just soften). Brown and season meat(italian sausage, IMO, though most ground or small chunk meat will do) and mix with your favorite spaghetti sauce(homemade would be best, but out of a jar is fine; add herbs to taste). Mix together three to four cheeses in a bowl(I'm fond of Ricotta/Cottage/Mozarella accented with a bit of cheddar, myself) and a bit of red pepper flake.
In a lasagna pan appropriate to the amount you want to make, alternate layers of sauce, noodles and cheese(in that order) until you have 3-4 layers. Top with a layer of sauce and some parmesan cheese. Bake for 45 minutes to an hour(based on the size you made).
Obviously, there are ways you can make it more complex and tastier, but that increases the effort. This method, as mentioned, takes about 15 minutes of actual work and results in something that blows those Stouffer's lasagnas out of the water.
