01 - Heat a drizzle of olive oil in a large pot or Dutch oven over medium heat. Add the ground turkey or beef and cook, breaking it apart with a wooden spoon, until evenly browned throughout, about 5 minutes.
02 - Add the diced onion, bell pepper, and minced garlic to the pot. Sauté until the vegetables soften and become fragrant, 3 to 4 minutes.
03 - Stir in the diced zucchini and continue cooking for an additional 2 minutes until it begins to soften.
04 - Add the tomato paste, chili powder, cumin, smoked paprika, black pepper, oregano, salt, and cayenne. Stir thoroughly and cook for 1 minute to toast and bloom the spices.
05 - Pour in the diced tomatoes with their juices, the drained beans (if using), and the broth. Stir well to combine all ingredients.
06 - Bring the mixture to a gentle simmer. Reduce the heat to low, cover the pot, and let it cook for 20 to 25 minutes, stirring occasionally to prevent sticking.
07 - Taste the chili and adjust salt, pepper, or spices as needed. Ladle into bowls and serve hot, garnished with fresh cilantro or a dollop of plain Greek yogurt if desired.
