While the chicken is cooking and resting, prepare burrito filling. Heat 1 tablespoon olive oil in a large skillet. Add onion and carrots and sauté for 4 minutes. Add celery,
green chilies and garlic and sauté an additional 2 minutes or until carrots are crisp-tender. Shred chicken and add to filling. Stir in 1/3 cup sour cream and hot sauce to taste until well combined.
