With layers of creamy ricotta, rich and hearty vegetable and meat sauce, tasty zucchini slices, and perfectly melted cheese, Freezer Zucchini Lasagna is a crowd-pleaser.
Preheat your oven.
Combine the cooked ground beef, onion, broccoli, cauliflower, spinach, garlic, ½ teaspoon salt, and pepper in a large skillet and sauté for about five minutes.
Add the marinara sauce to your meat/vegetable mixture and simmer.
On a parchment-lined cookie sheet, spread zucchini slices in a single layer and bake.
