To a large pan, add the ground turkey and season with a little salt and pepper. Sauté over medium heat, until cooked, about 7-9 minutes.
Meanwhile, drain and rinse the beans, open the tomatoes and collect your spices.
Add the beans, diced tomatoes, pumpkin and corn, and stir to combine. If your diced tomatoes don’t have much liquid, or if your chili gets too thick during cooking, add a cup or so of water or broth to thin.
For a quick cook, bring the chili to a simmer over high heat, then reduce to medium and simmer, covered, for about 15 minutes, lowering the heat, if necessary. Stir in the tomato paste, starting with 2 tablespoons and adding more, to taste. Stir in the vinegar, taste, and adjust seasonings, if desired. If you have a little more time, let the chili simmer, covered, over the lowest heat for up to an hour.
Set your toppings out and let everyone load up their servings with their own preferred toppings (kids especially like dipping tortilla chips into their bowls). Enjoy!
Slow cooker version: Except for the vinegar, add all of the ingredients to a slow cooker, along with a cup of water of broth, and cook for 7 to 8 hours on low. Add the vinegar, taste, and adjust seasonings, if desired.
