In a large pot, cook the ground turkey and onion until the turkey is cooked through and browned, breaking up the meat as it cooks. Stir in taco seasoning and ranch mix.
Add the black beans, kidney beans, corn, diced tomatoes, Rotel, and chicken broth to the pot. Stir everything together, cover the pot, and simmer for 20 minutes, stirring occasionally.
Stir once more before serving warm. Garnish with chopped parsley or cilantro is desired.
