In a large pot, heat 1 tablespoon of oil over medium heat. Add the diced onion and sauté until it becomes translucent, about 5 minutes. Stir in the minced garlic, chili powder, cumin, and oregano, and cook for an additional minute until fragrant.
Next, add the rinsed and drained Great Northern beans to the pot. Pour in the broth and stir well to combine all the ingredients. Bring the mixture to a gentle simmer.
Once the chili is simmering, add the chopped cooked turkey. Stir everything together, ensuring the turkey is evenly distributed.
Add the diced Roma tomato and cilantro to the pot. Season with salt and pepper to taste. Allow the chili to simmer for 15-20 minutes, stirring occasionally.
Once your White Bean Chili with Turkey is ready, ladle it into bowls. Garnish with additional chopped tomatoes, cilantro, and a wedge of lime if desired. Enjoy!
