Preheat the oven to 425 degrees.
Toss the sliced sweet potato with 2 teaspoon olive oil, ½ teaspoon kosher salt, ½ teaspoon cumin, and ½ teaspoon cinnamon. Add to a baking sheet and roast for about 25 minutes or until soft and fork-tender.
Meanwhile, add all of the turkey meatball ingredients to a bowl and mix together with your hands or a spatula until all spices and the onion are evenly combined into the ground turkey. Form the ground turkey into either meatballs or burger patties (makes about 10 meatballs or 4 patties).
To a skillet on medium heat, add 2 teaspoon olive oil. Once heated, add the meatballs or burger patties. For meatballs, cook for about 15 minutes total, rotating sides every 3-4 minutes until cooked through. For burger patties, cook for about 9 minutes total, 4-5 minutes on each side until cooked through.
Meanwhile, prepare the bowls. Toss the arugula with 2 teaspoon olive oil, the juice of 1 lemon, and salt/pepper to taste.
To serve, add the salad to the bottom of your bowl. Then, add the roasted red bell peppers, crumbled feta cheese, and any other vegetables or sauces. Add the sweet potato “fries” and turkey meatballs or burgers. My favorite bite has a little bit of everything!
