Preheat your oven to 425°F.
Cut the red bell pepper, zucchini, and yellow onion into bite-sized pieces.
Place the chopped vegetables on a baking sheet, drizzle with olive oil, and season with a pinch of salt, black pepper, and garlic powder.
Roast the vegetables for about 20-25 minutes until they are tender and slightly caramelized, stirring halfway through.
While the vegetables roast, heat a non-stick skillet over medium heat and add the lean ground turkey.
Cook the turkey, breaking it up with a spatula, until it is fully browned and cooked through, about 7-10 minutes. Season with additional salt and pepper to taste.
Once the vegetables are roasted, combine them in the skillet with the cooked turkey, stirring to mix evenly.
Allow the skillet to heat through for an additional 2 minutes, absorbing the flavors.
Serve warm and enjoy your nutrient-packed, flavorful skillet dish.
