Bring a large pot of salted water to the boil then cook lasagna noodles according to package directions. (add a teaspoon of olive oil to the water so the noodles do not stick together). Drain then lay flat on a sheet of aluminum foil.
Vegetable Red Sauce

Assemble
Spoon just enough vegetable mixture into the baking dish to lightly cover the bottom Arrange four noodles lengthwise and side by side to cover the bottom. (If the noodles are short on one end, you may need to cut an extra noodle and place into the dish to cover where the other noodles have not).
Spread about half of the ricotta cheese mixture over the noodles. Top with a third of the vegetable mixture. Add another layer of four noodles then repeat with remaining cheese and vegetables. Finish with a final layer of noodles, vegetables, Parmesan cheese and mozzarella cheese.
