In a pan over low-medium heat, add olive oil, ground meat and seasoning (garlic powder, Italian seasoning, black pepper, salt, and paprika). Let it cook through and remove any excess liquid/ fat.
For the sauce, add olive oil to a saucepan over low heat. Add minced garlic and let it cook until brown while stirring constantly. Add chopped onion and cook until translucent. Then add tomato paste, water, and seasoning.
Preheat the oven to 325F.
For assembly, cut zucchinis in thin slices lengthwise (about 1/8 inch). Add 3 tablespoons of sauce to the bottom of your baking pan (I used an 8x8 inch pan) and spread it out to cover the surface. Add a layer of overlapping zucchini slices, cheese, meat, and repeat until ingredients run out.
