01 - Heat a drizzle of oil in a large pot or Dutch oven over medium heat. Add diced onion and red bell pepper, and sauté for 4 to 5 minutes until softened.
02 - Incorporate minced garlic and jalapeño (if using), and cook for 1 minute until fragrant.
03 - Add ground turkey or chicken, breaking it apart with a spoon; cook until evenly browned and fully cooked, about 6 to 8 minutes.
04 - Stir in tomato paste, chili powder, cumin, smoked paprika, oregano, salt, and black pepper. Cook for 2 minutes to deepen the flavors.
05 - Add diced tomatoes with their juices, rinsed black beans, kidney beans, and broth. Stir well to combine.
06 - Bring mixture to a gentle boil, then reduce heat and simmer uncovered for 30 minutes, stirring occasionally, until thickened and flavors are melded.
07 - Taste and adjust seasonings as needed. Serve warm, garnished with cilantro, green onions, and a spoonful of Greek yogurt or light sour cream if desired.
