Make the meatballs: In a bowl, mix sausage, ground turkey, Mozzarella cheese, parmesan, egg, parsley, cilantro, olive oil, onion powder, garlic powder, smoked paprika, cayenne and bouillon paste (if not using paste, sub in 1/2 teaspoon of salt) and Italian seasoning. Form into 1-inch balls.
Cook the meatballs: Heat olive oil in a large skillet. Brown the meatballs on all sides until golden and cooked through (about 10–12 minutes). Remove and set aside.
Cook the pasta: While the meatballs are sizzling, boil your pasta to al dente. Reserve 1/4 cup pasta water, then drain. (Or cook zoodles until just tender!)
Make the lemon butter sauce: In the same skillet, melt butter with olive oil over medium heat. Add garlic and thyme and cook for 1 minute. Stir in lemon zest, juice, chicken broth and reserved pasta water.
Finish it off: Toss in the pasta and parmesan. Stir until creamy and coated. Top with meatballs, a sprinkle of parsley, and maybe a little extra parmesan (because when is it ever too much?).
