Heat a large skillet over medium-high heat. Add turkey and brown, breaking up the meat into small crumbles until just cooked through. Drain and reserve in a separate bowl.
In the same skillet, warm the olive oil over medium heat and sauté the onions, pepper and garlic until onion is tender and translucent.
Add turkey back to the skillet and add remaining ingredients. Stir to combine and simmer over medium-low heat for 15 minutes. Taste for seasoning and add more salt and pepper if needed.
