Step 1

Place olive oil, lime juice, onion, tarragon, salt, and hot sauce into a large, resealable plastic bag; shake to mix. Add chicken thighs, coat with marinade, squeeze out air, and refrigerate for at least 4 hours.

Step 2

Preheat an outdoor grill for medium heat and lightly oil grate. Remove chicken from marinade, and shake off excess. Discard remaining marinade. Season with salt and pepper.

Step 3

Grill chicken for about 30 minutes, or until no longer pink in the center. Chicken thighs don't dry out easily, so don't be afraid to cook them a bit longer if needed.
