Heat the extra virgin olive oil in a large pot or Dutch oven over medium-high heat.
Add the ground turkey to the pot and cook until browned, using a wooden spoon to break the meat into small crumbles.
Stir in the diced yellow onion and red bell pepper, sautéing for about 4 minutes until the vegetables are soft and translucent.
Add the cubed sweet potatoes, rinsed black beans, diced tomatoes (with their juices), and vegetable broth to the pot.
Season the mixture with chili powder, ground cumin, garlic powder, sea salt, and black pepper, stirring well to combine.
Bring the chili to a gentle boil, then reduce the heat to low and cover the pot with a lid.
Simmer for 20 to 25 minutes, or until the sweet potatoes are fork-tender and the flavors have melded together.
Remove from heat and let sit for 5 minutes before serving to allow the sauce to thicken slightly.
