Cook your lasagna noodles according to the package directions. When cooked drain and coat with olive oil and place on a cookie sheet.
Spray a 9x13 baking dish with cooking spray.
Pour 1 cup of sauce on the bottom and cover it with 5 cooked sheets of lasagna, ½ cup of ricotta, shredded mozzarella, and 2 tablespoon of Parmigiano cheese.
Repeat for 2 more layers. On the top layer add the remaining sauce but reserve the leftover cheese.
Smoke uncovered for 30 Minutes to 1 hour.
Top with the remaining mozzarella and Parmigiano cheese and cover with foil.
Up the temp to 350F or 176C and cook for 1 hour.
Uncover and top with the remaining cheese. Cook uncovered for an additional 15-25 minutes or until the cheese is all melted and bubbly. Watch out for burning.
