Preheat the oven to 425 degrees. Toss the sweet potatoes with olive oil and 1 tbsp taco seasoning. Spread out in a single layer on a baking sheet. Bake for 18-25 minutes or until the potatoes are tender and cooked through. Shake the pan a few times while cooking.
Heat a nonstick skillet over medium high heat. Add the ground turkey, onions, bell pepper, and taco seasoning. Cook for 7-10 minutes, breaking up the turkey as it cooks until it is cooked through. Note, the onions and peppers will be tender crisp. If you prefer softer peppers and onions, cook them for 5 minutes before adding the turkey. Remove and set aside. Wipe the skillet clean.
