1Steam the cubed potatoes until tender, about 15 minutes.
2While potatoes are cooking, spray a wide non stick skillet or wok with non stick spray. Add chicken and cook over high heat until no longer pink, about 5 minutes. Continue to cook until chicken is lightly browned. Remove chicken from skillet. Add vegetable oil and steamed potatoes to same skillet. Cook until potatoes are lightly browned, stirring often.
3Stir in cooked chicken, corn, beans, onions, and salsa. Reduce heat to medium and cook until heated through, 4-5 minutes. Stir in coriander. Remove from heat and serve immediately.
