How to Make It
Heat the oil in a large Dutch oven over medium-high. Sprinkle chicken with black pepper and salt; cook, turning to brown on all sides, 5 minutes. Place chicken in a bowl (do not wipe out pan).
Add potatoes, onion, and bell pepper to pan; cook, stirring occasionally, 3 minutes. Add garlic; cook 1 minute. Stir in curry paste and kale; cook until kale wilts, about 2 minutes. Stir in coconut milk and stock; bring to a boil. Reduce heat, cover, and cook until potatoes are tender, about 15 minutes. Return chicken to pan; cook 5 minutes.
Divide quinoa among 4 shallow bowls. Top evenly with chicken mixture and cilantro leaves.
