In a large Dutch oven over medium/high heat, brown the ground turkey and chorizo in the olive oil, stirring often.
Season with ½ teaspoon salt and ¼ teaspoon black pepper.
Add the bell peppers, onions, and garlic and cook, stirring occasionally, for approximately 3-4 minutes.
Add the remaining salt, pepper, spices, cocoa powder, and tomato paste to the pan, stirring occasionally for 1-2 minutes.
Reduce the heat to medium/low and stir in the remaining ingredients, in the order given.
Allow the mole turkey chili to simmer, uncovered, for at least 30-40 minutes, stirring occasionally.
Right before serving stir in 2 tablespoons of butter.
Ladle the chili into large bowls and garnish with a dollop of sour cream and a bit of shredded cheddar cheese if desired.
