In a large bowl, combine ground turkey, cheese, 4 cloves minced garlic, Italian seasoning, bouillon, red chili pepper flakes, chopped cilantro, salt and pepper. Mix well with your hands and use a medium cookie scoop or tablespoon to form 1 - 1 1/2 inch meatballs. Arrange on a plate and set aside.
Melt 2 tablespoons butter in a large skillet over medium-low heat. Add meatballs (in batches if necessary - you don't want to overcrowd them) and cook for 2/3 minutes per side, until browned and cooked through. While cooking, baste the meatballs with the pan juices. Remove to a clean plate and set aside.
In the same skillet melt remaining tablespoon butter; then add lemon juice, hot sauce, remaining minced garlic, and red pepper flakes (if you want). Add the zoodles and cook for 3 or 4 minutes, stirring regularly, until zucchini is done but still crisp and juices have reduced a bit. Adjust seasoning with salt and pepper and garnish with more cilantro or parsley if you like.
Push zucchini on one side of the skillet and add the meatballs back to the pan and reheat for a minute or two. Serve immediately with extra lemon slices.
