Preheat the oven to 400° F and line a large sheet pan with parchment paper.
Cut the stem off of each zucchini and cut in half along the length of the zucchini, resulting in two long halves. Scoop out the inside of each piece and place cut side down onto the parchment paper lined sheet pan. Bake at 400° F for 15-20 minutes until softened to your liking.
While the zucchini bakes, prepare the pizza stuffing. Heat the avocado oil in a large pan over medium heat. When hot, add garlic and saute for 1-2 minutes until fragrant. Add the onion and red pepper and saute for 5-7 minutes until the onion begins to turn translucent. Add ground pork and break into small pieces until browned and cooked through.
Add the pizza sauce and all of the spices, from sea salt through oregano. Mix to combine and simmer for 10 minutes.
When the zucchini is done, use a spoon to fill the insides of each zucchini half with the pizza mixture. Top with toppings of choice and serve! If not paleo or on Whole30 and you want to add cheese, now is the time to do so. Add cheese to each zucchini half as desired and place back in the oven until the cheese has melted.
