Season chicken with curry powder, salt, and pepper.
In a large non-stick skillet, heat 2 Tbsp. canola oil over medium-high heat. Sauté chicken until just cooked, about 7 to 8 minutes. Remove to plate and set aside.
Add 1 Tbsp. canola oil to the pan. Sauté garlic and ginger along with peppers and celery. Sauté for 5 to 6 minutes. Stir occasionally.
Add coconut milk, lemon zest, and mango, along with chicken. Heat through. Stir in basil.
Serve with short-grain rice.
