• Prepare the grill for direct cooking over high heat (450° to 550°F).
  Prepare the grill for cooking over high heat (500°F).
• Lightly brush the tomatoes, onion quarters, bell pepper, and scallions with oil. Brush the cooking grates clean. Grill the vegetables over direct high heat, with the lid closed, until they are charred all over and tender, turning as needed. Remove the vegetables from the grill as they are done. The onion and bell pepper will take 10 to 12 minutes, the tomatoes will take 6 to 8 minutes, and the scallion will take 2 to 4 minutes. Place the bell pepper in a bowl and cover with plastic wrap. Let stand for 10 to 15 minutes.

• In the bowl of a food processor or blender, process the tomatoes, onion, garlic, chipotle chiles, and lime juice until smooth. Season with salt. Pour the salsa into a glass or stainless steel bowl and set aside.
• In a small bowl combine the rub ingredients. Lightly brush the chicken thighs on both sides with oil and season evenly with the rub.
• Brush the cooking grates clean. Grill the thighs over direct high heat, with the lid closed, until the meat is firm and the juices run clear, 6 to 8 minutes, turning once or twice. Transfer to a cutting board and let cool.

• When the thighs are cool enough to handle, cut them into ⅓-inch pieces and put them in a large bowl along with ⅓ cup of the salsa. Remove and discard the stem, skin, and seeds from the bell pepper. Chop the bell pepper and the scallions and add them to the bowl; toss to combine. Season with salt and lime juice.
