01 - Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the ground turkey and cook, breaking it up with a spatula, until browned and cooked through, about 5–6 minutes. Transfer turkey to a plate and set aside.
02 - In the same skillet, add the remaining olive oil. Sauté the onion and red bell pepper until softened, about 3–4 minutes.
03 - Stir in the garlic and cook for 30 seconds until fragrant.
04 - Add the diced zucchini, salt, black pepper, and red pepper flakes. Sauté for 4–5 minutes, stirring occasionally, until zucchini is just tender but not mushy.
05 - Return the cooked turkey to the skillet. Stir in the chopped basil and lemon juice. Cook for another 1–2 minutes until everything is heated through and flavors meld.
06 - Taste and adjust seasonings as needed. Serve hot, garnished with extra basil and Parmesan cheese if desired.
