Use the sauté function on your Instant Pot to brown one side of the ground turkey (about 4-6 minutes).
Once one side has browned, flip the ground turkey and add the diced peppers. Leave the turkey and peppers alone for an additional 4-5 minutes to brown the other side.
Once both sides of the ground turkey have browned, turn off the Instant Pot. Add the tomato sauce and balsamic vinegar, deglazing the pot completely, before adding the chili seasoning blend. Stir until everything is evenly incorporated.
Add the beans and broth before sealing the Instant Pot and pressure cooking on high for 15 minutes with quick release (vent immediately after cooking). Give the turkey chili a stir and salt and pepper to taste.
Serve with corn chips or baked tortilla chips, shredded cheese, fat free Greek yogurt or sour cream, and scallions or freshly diced chiles.
