Preheat large non-stick skillet on high heat and swirl oil to coat. Add zucchini, sprinkle with salt and pepper and cook for 5 minutes, stirring occasionally and allowing to brown. Transfer to a medium bowl and set aside.
Return skillet to the stove and add ground turkey. Cook for 5 minutes, constantly breaking into small pieces and stirring.
Add marinara sauce. Stir, bring to a boil and let it simmer for 3 minutes on low heat.
Add previously cooked zucchini and stir again. Sprinkle with cheese and place under the broiler for 3 minutes (if your skillet allows) or just cover with a lid and let cheese melt.
Serve on its own for a low carb meal or over spaghetti for a full meal.
Notes
Store: Refrigerate covered for up to 3 – 4 days. Do not freeze.
To reheat: Simmer on low heat in a skillet for 5 minutes covered. If you use non-stick skillet you should not need any water or oil to reheat the dish as again zucchini will release water.
