01 - Heat a large pot or Dutch oven over medium heat. Add the ground turkey and cook, breaking it up with a spoon, until browned and cooked through, about 5 to 6 minutes. Drain excess fat if necessary.
02 - Add diced onion, red bell pepper, garlic, and jalapeño (if using) to the pot. Cook for 4 to 5 minutes, stirring occasionally, until the vegetables soften.
03 - Stir in chili powder, cumin, smoked paprika, oregano, salt, black pepper, and cayenne pepper. Cook for 1 minute until the spices release their aroma.
04 - Pour in diced tomatoes with their juices, kidney beans, black beans, corn kernels, and broth. Mix thoroughly to combine all components.
05 - Bring the mixture to a gentle simmer, reduce heat to low, cover, and cook for 20 to 25 minutes, stirring occasionally to blend flavors.
06 - Taste the chili and adjust seasoning as desired before serving.
07 - Serve hot, garnished with optional toppings such as cilantro, green onions, shredded cheddar cheese, sour cream, or lime wedges.
