Add coconut oil to a medium high heat pan and cook the ground beef. Add the tomato sauce to the ground beef and combine. Set aside. Using a mandolin slicer, slice the zucchini into as many thin slices as possible and set aside.
Add the ricotta, Parmesan, garlic cloves, salt, pepper, and egg to a processor and blend until fully combined. In a oven safe skillet or casserole dish first make a layer of the ground beef. Make two layers of the zucchini criss crossing.
Add a generous layer of the ricotta mixture. Sprinkle on some of the shredded mozzarella. Repeat this a second time (we made two full layers in our 6 inch skillet). Last layer should be the mozzarella cheese.
Bake in a 350 degree oven for 30 minutes or until cheese is browned.
