Prepare a seasoning mix: add the chili powder, salt, garlic powder, cumin, black pepper and cayenne pepper (if using) to a small bowl. Stir to combine well.

Heat the oil in a large pot over medium heat. Add the onions and cook 4-5 minutes, stirring frequently.

Add the garlic and cook 1 minute, stirring frequently.

Raise the heat to medium-high and immediately add the ground turkey and sprinkle with the prepared seasoning mix. Stir well to combine the turkey with the onions and spices.

Arrange the turkey into a layer and cook for 3 minutes.

Stir well and break-up any large pieces. Arrange it into a layer again, cook for another 2-3 minutes, or until browned and any liquid rendered has cooked away.

Add the diced tomatoes, white beans and chicken broth to the pot. Stir well.

Bring the liquid to a boil (it will take about 4-5 minutes to start boiling), then lower the heat to medium-low, cover and simmer the chili for 30 minutes. Stir occasionally.

Uncover the pot and cook for an additional 10-20 minutes or until the chili thickens and is saucy, not soupy. How long this will take depends on how much liquid is left after the initial cooking time. Keep an eye on it and stir it often, especially as it starts to thicken, to prevent sticking on the bottom.

Taste the chili and add salt if needed. As a reference we did not add extra to ours.
