These grilled chicken fajitas are a crowd-pleasing meal that's easy to make. To make the marinade, combine lime juice, garlic, cumin, chili powder, salt, and olive oil in a food processor. Pulse until smooth, then pour over the chicken and let it marinate for at least 30 minutes. Grill the chicken until cooked through, then slice into strips. Serve the chicken on warm tortillas with sautéed bell peppers and onions, shredded cheese, and sour cream.
