Prep the onion, bell pepper, zucchini, garlic, and spinach before heating the skillet. Keep the broth, seasonings, and thermometer within reach.
Heat a 10-12-inch skillet over medium-high heat. Add olive oil, then add the ground turkey. Break it into small crumbles and cook for about 4-5 minutes, stirring occasionally.
Add onion, bell pepper, garlic, paprika, oregano, cumin, salt, and pepper. Cook for about 2 minutes, stirring so the vegetables begin to soften.
Add zucchini and broth. Stir, cover, and cook for approximately 3 minutes, until the zucchini is tender-crisp and the turkey reaches a safe internal temperature.
Stir in spinach and cook uncovered for 1-2 minutes until wilted. If the skillet looks watery, continue cooking uncovered briefly to reduce excess liquid.
Remove from heat. Add lemon juice, taste, and adjust salt and pepper. Serve immediately or portion for meal prep.
USDA food safety guidance supports cooking ground poultry to a safe minimum internal temperature of 165°F, measured with a food thermometer.
