01 - In a large pot or Dutch oven, warm a drizzle of cooking oil over medium heat. Add the ground turkey and cook until thoroughly browned, using a spoon to break it into small pieces, approximately 5 minutes.
02 - Add the diced onion, bell pepper, and minced garlic to the pot. Sauté the mixture until the vegetables have softened, which will take about 4 to 5 minutes.
03 - Stir in the chili powder, ground cumin, smoked paprika, dried oregano, salt, black pepper, and optional cayenne pepper. Cook for 1 minute, stirring constantly, until the spices become fragrant.
04 - Incorporate the tomato paste, undrained diced tomatoes, drained and rinsed kidney beans, and chicken broth. Stir all ingredients to combine thoroughly and bring the mixture to a gentle simmer.
05 - Add the uncooked elbow macaroni to the simmering mixture. Stir well, then cover the pot and reduce the heat to medium-low. Continue to simmer, stirring occasionally, until the pasta is tender, approximately 10 to 12 minutes.
06 - Reduce the heat to its lowest setting. Stir in the milk and shredded cheddar cheese until the cheese is completely melted and the sauce becomes creamy and smooth.
07 - Taste the chili mac and adjust seasonings as desired. Serve hot, optionally garnished with additional shredded cheese or fresh chopped cilantro.
