Start by dicing the onion and bell pepper.

In a large pot, heat olive oil over medium heat.

Sauté the onion and bell pepper for about 5 minutes, or until softened and fragrant.

Add the ground turkey to the pot, breaking it apart as it cooks for about 7-10 minutes.

Stir in the chili powder, cumin, garlic powder, salt, and pepper, cooking for 1 minute.

Add the diced tomatoes and kidney beans, mixing everything well.

Bring to a gentle boil, then reduce heat to low, cover partially, and simmer for at least 30 minutes.
