9Cut the chicken breast into bite-sized pieces.
In a large bowl, mix the olive oil, smoked paprika, chili powder, cumin, garlic powder, onion powder, and cayenne pepper.
Add the chicken pieces to the bowl and toss to coat evenly with the spice mixture. Let it marinate for at least 30 minutes.
Preheat the grill to medium-high heat.
Thread the marinated chicken pieces onto skewers, alternating with chunks of bell pepper and red onion.
Grill the skewers for about 10-12 minutes, turning occasionally, until the chicken is cooked through and has a nice char.
Remove the skewers from the grill and sprinkle with chopped cilantro.
Serve the skewers with lime wedges on the side for squeezing over the top.
