Coat a large pot or Dutch oven with olive oil over medium-high heat.
Add the onion and bell pepper and sauté, stirring occasionally, for about 5 minutes, or until the onion softens.
Add the garlic, and cook until fragrant, about 30 seconds.
Add the ground turkey and use a spatula to break up the meat as it cooks. Continue to cook about 6 to 7 minutes, until no longer pink.
Add pumpkin puree, diced tomatoes, broth, chili powder, cumin, black pepper, stir together until well combined.
Reduce heat to low, cover and simmer for 20 to 30 minutes, stirring occasionally.
Top with your toppings of choice and enjoy! Store leftovers in the fridge for up to a week.
