Directions

1. Grind coriander, cumin and fennel seeds in a spice grinder or with a mortar and pestle until the mixture resembles coarsely ground pepper. Transfer to a medium bowl and add cornstarch, salt and turmeric; stir to combine. Add chicken and stir until coated with the spice mixture.
2. Preheat a large flat-bottom wok or cast-iron skillet over high heat. Add 2 tablespoons oil. When the oil is shimmering, add carrots, bell pepper, onion, garlic and chiles. Cook, stirring, until the vegetables begin to brown, 4 to 6 minutes. Transfer to a plate.
3. Reduce heat to medium-high and add the remaining 1 tablespoon oil to the pan. Add the chicken and seasonings from the bowl and cook, stirring, until no longer pink in the middle, 5 to 7 minutes. Stir in the vegetables, lime juice and mint and cook until heated through, about 30 seconds.
