Barry,

If you're really into lasagna, I suggest trying the Cook's Illustrated quick lasagna recipe. The goal was to make a passable lasagna without spending the whole day in the kitchen. When I made it, it took about 45 min. of prep time and about the same amount of time in the oven. And it was way better than any store-bought frozen crap.
