1. Heat olive oil in a large frying pan.
2. Add onions, cabbage, and salt, and sauté over low heat for 20 minutes, stirring occasionally. Turn the heat to high in the last minute to give the onions and cabbage a caramel color and flavor.
3. Halfway through the sautéing time, preheat your Crock-Pot by turning it on low and spraying it with cooking spray. Mix together the pizza sauce, honey, and lemon juice. Taste and, if desired, add two tablespoons brown sugar for a sweeter sauce. (I didn’t.) Add to Crock-Pot.
4. Mix together the meat, turkey, egg, almond flour, spices, and the onion-cabbage mixture. Form into golf-ball-sized meatballs. Carefully drop into the sauce. Cook on low for six hours. (If you’re not home, you can leave it up to eight hours, but they’re ready after six.)
