Whenever I cook lasagna I make a HUGE one and I tend to do it on a weekend or an afternoon when I know I will be home for the rest of the night. If you are going to go to the trouble to make lasagna, why not have it be big enough to last for a few meals? When I make this lasagna it lasts my family of 4 (2 of which are children) 3 whole dinners! We eat it fresh out of the oven one night and then I usually freeze the other 2 sections for 2 other nights. You pop it in the oven for an hour from the freezer, make a salad, and you have a fantastic dinner!
