Heat 2 TBSP olive oil in large skillet over med high heat. Cook ground turkey, stirring occasionally to break up. Remove from pan with slotted spoon and drain if necessary.
Add additional 1 TBSP olive oil to pan and lower heat to medium. Add chopped onions, celery, and carrots. Cook, stirring often, until vegetable are al-dente tender. Add garlic and cook for another 2-3 minutes.
Add meat back to skillet. Stir to combine with veggies.
Add in the chicken broth, canned tomatoes, and tomato paste. Stir until combined.
Gently stir in drained beans and spices (chili powder, salt, pepper, cumin, red chili flakes, & brown sugar).
After turkey chili comes to a low boil, reduce pan and continue to simmer for 20-30 minutes. Chili will thicken slightly and the flavors will blend. At this point, you can turn off the heat and reheat chili right before serving.
Right before serving, cook pasta.
Serve chili on top of pasta and top with grated cheese, chopped red onion, and sour cream.
Enjoy!
