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, approximately 5 minutes.
02 - Add the diced onion, bell pepper, and minced garlic to the pot. Sauté until the vegetables have softened and the onions turn translucent, 3 to 4 minutes.
03 - Stir in the diced zucchini and continue cooking for an additional 2 minutes, allowing it to begin softening.
04 - Add the tomato paste, chili powder, ground cumin, smoked paprika, black pepper, dried oregano, salt, and cayenne pepper. Stir thoroughly and cook for 1 minute to toast and bloom the spices, releasing their full flavor.
05 - Pour in the diced tomatoes with their juices, the rinsed beans (if using), and the broth. Stir everything together until well combined.
06 - Bring the mixture to a simmer, then reduce the heat to low. Cover the pot and let it simmer gently for 20 to 25 minutes, stirring occasionally to prevent sticking, until the flavors have melded and the vegetables are tender.
07 - Remove from heat and taste the chili. Adjust salt, pepper, or cayenne as needed to suit your preference.
08 - Ladle the chili into bowls while hot. Garnish with fresh cilantro or a dollop of plain Greek yogurt if desired.
