1/4 cup oil
1 pound ground beef
2 cups Marinara Sauce
16 ounces whole milk mozzarella cheese, shredded
3/4 cup Parmesan cheese, grated, about 3 ounces
Salt and pepper, to taste
Cut the ends off and peel the eggplant. Slice the eggplant lengthwise into 1/2-inch slices. this should yield about 6 to 8 slices from each eggplant. Brush both sides of the eggplant slices with oil to coat. Place them in a single layer on a baking sheet, you may need to do them in two batches. Broil about 3 to 5 minutes per side until tender, and a little browned. Watch them closely, because they can burn quickly. Lightly sprinkle them with salt after removing from the oven. Brown the ground beef, and season to taste with salt and pepper. Add the marinara sauce and heat through. Layer everything in a greased 7x9x3-inch baking dish in this order: 1/3 of the eggplant slices, 1/3 of the sauce, 1/3 of the mozzarella. Repeat the layering two more times then sprinkle with the Parmesan cheese. If you don't have that size baking dish, use a 9x13-inch baking dish and make 2 layers of each ingredient using half of everything per layer in the same order. Bake at 350°F about 30 minutes, or until the cheese is bubbly.
