Add all of the ingredients from olive oil to zucchini to a crockpot and stir to combine. Turn crockpot onto low for 8 hours (or high for 4 hours). At 6 hours, add the kale and macaroni noodles (or at hour 3 if cooking on high). Cover with lid again and let finish cooking the final 2 hours. Add more salt and black pepper to taste if needed.
