Here's a suggestion: Lasagna for busy people. Make a huge pot of your best Italian meat sauce. (For me, that's lots of garlic and onion, sauteed grass-fed ground beef, oregano, canned tomatoes and tomato paste, salt & pepper to taste. But I like ChuckKD's idea of multiple meats and I'd use sausage if it wasn't too rich for me.) Make at least 2 quarts of sauce. Maybe four.
Boil a pot of spaghetti and have some with the sauce, and throw the rest of the sauce in the freezer.
Then, on another day, boil the lasagna noodles, lay them in a pan, add sauce and cheese, and more cheese on top, and bake.
And if you don't eat it all, freeze it again.
Lasagna is time-consuming, so why not make it in two days - maybe even a week apart, first the sauce, then the dish?
