Heat a large skillet over high heat. Add 1 teaspoon oil; swirl to coat. Add chicken; cook 1 minute on each side. Remove chicken from pan; cut into thin slices. Add onion, broccoli, and bell pepper to pan; stir-fry 2 minutes; add garlic. Stir-fry another 2 minutes or until vegetables are lightly browned. Reduce heat to medium-high. Combine remaining 1 teaspoon oil, coconut milk, and next 7 ingredients (through cumin) in a small bowl, stirring with a whisk. Add chicken and coconut milk mixture to pan; cook 30 seconds. Sprinkle evenly with cashews.
