Substitute 6 ounces no-boil lasagna noodles (12) for the lasagna noodles. Increase milk to 2 cups and spread 1/2 cup of the vegetable mixture in the bottom of the dish before adding the first layer of noodles. Continue as above.
After assembling, cover the unbaked lasagna with foil and chill up to 48 hours. Bake, covered, in a 350 degree F oven for 30 minutes. Uncover and bake 30 to 35 minutes more or until heated through. Let stand for 10 minutes before cutting.
