For an authentic touch, add a layer of 1 cup ricotta cheese under one of the sauce layers when assembling lasagne.
Substitute any fresh vegetables you have on hand, such as green or red peppers, broccoli or squash, for any/all of the vegetables listed in recipe. For best results, use a total of 8 cups chopped vegetables.
Save on the lasagne assembly time by preparing the sauce the day before. Then, refrigerate until ready to use to assemble the lasagne and bake as directed.
