01 - In a large pot or Dutch oven, drizzle a small amount of oil and heat over medium flame. Add the ground turkey and cook until it is thoroughly browned, breaking it into smaller pieces with a spoon for approximately 5 minutes.
02 - In the same pot, add the diced onion, bell pepper, and minced garlic. Sauté these vegetables until they have softened, which should take about 4 to 5 minutes.
03 - Stir in the chili powder, ground cumin, smoked paprika, dried oregano, salt, black pepper, and cayenne pepper (if desired for added heat). 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 into the pot. Stir thoroughly to combine all ingredients, then bring the mixture to a gentle simmer.
05 - Add the uncooked elbow macaroni to the simmering mixture. Stir well, then cover the pot and continue to simmer on medium-low heat. Stir occasionally to prevent sticking, cooking until the pasta is tender, typically 10 to 12 minutes.
06 - Reduce the heat to low. 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 cheese and adjust the seasoning as needed. Serve hot, optionally garnished with additional shredded cheese or fresh chopped cilantro.
