To prepare sunshine chicken rice, you'll first need to prepare the chicken. Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add 2 pounds of chicken to the skillet and cook, turning occasionally, until chicken is no longer pink, 8 to 10 minutes. Remove chicken from pan and set aside. In the same skillet, add 2 cups of water and 1 teaspoon of kosher salt. Bring to boil, then reduce heat to medium and simmer, covered, for 30 to 40 minutes, stirring occasionally. Serve with lemon wedges and sour cream, if desired.
