Step 1

Mix coriander, cumin, termeric, and red pepper flakes in a small bowl; set aside. Heat 2 Tbsp. oil in a large nonstick skillet over medium. Add garlic and cook, tossing occasionally, until golden brown all over, about 5 minutes. Increase heat to medium-high. Season chicken with kosher salt and add to skillet. Cook, tossing occasionally, until chicken is golden brown and nearly cooked through, about 3 minutes. Remove from heat and sprinkle reserved spice mix over. Toss several times to coat and let chicken sit in skillet until cooked through, about 1 minute longer. Transfer to a plate and let cool slightly.

Step 2

Whisk lime juice and remaining 5 Tbsp. oil in a small bowl; season dressing with kosher salt.

Step 3

Arrange lettuce, chicken, avocado, mango, onion, and tomatoes on a platter. Drizzle with dressing. Sprinkle with sea salt and red pepper flakes and scatter herbs over.
