Warm the skillet. Heat olive oil in a large skillet over medium-high heat until it shimmers.
Swirl to coat the pan.
Brown the turkey. Add the ground turkey, breaking it up with a spatula. Season with a pinch of salt and pepper. Cook until no longer pink and lightly browned in spots, about 5–6 minutes.
If there’s excess liquid, let it cook off.
Add aromatics. Stir in the diced onion and minced garlic. Cook until the onion softens and turns translucent, about 3 minutes. Keep stirring so the garlic doesn’t burn.
Season it up. Sprinkle in the smoked paprika, Italian seasoning, remaining salt, black pepper, and red pepper flakes if using.
Stir to coat the turkey and onion with the spices.
Cook the veggies. Add the zucchini and bell pepper. Cook, stirring occasionally, until the zucchini is just tender but still has a little bite, about 4–6 minutes. Avoid overcooking to prevent mushiness.
Make it saucy. Whisk the tomato paste into the chicken broth, then pour it into the skillet.
Stir and let it simmer for 2–3 minutes until slightly thickened and glossy.
Brighten and finish. Turn off the heat and stir in the lemon juice. Taste and adjust seasoning with more salt, pepper, or a pinch of red pepper flakes. Fold in the chopped parsley or basil.
Serve. Spoon into bowls and finish with your favorite topping. Parmesan adds savory depth, feta brings tang, and Greek yogurt adds creamy coolness.
