In a large pot, cook beef until done. Drain the meat, then add all tomato ingredients, bone broth, red pepper flakes, and basil. Let simmer over low heat.
Preheat oven to 350 degrees. Smear the coconut oil on the bottom of a pan, followed by a layer of zucchini. Add a layer of meat, then repeat with another layer of zucchini, finishing with a layer of tomato mixture.
Place in oven, and cook for 30-45 minutes, or until done.
