1Preheat the grill to medium-high heat.
In a large bowl, combine the cubed chicken breast, olive oil, paprika, garlic powder, salt, and pepper. Mix well to coat the chicken evenly.
Thread the chicken cubes, red bell pepper pieces, green bell pepper pieces, and red onion pieces alternately onto skewers.
Place the skewers on the preheated grill.
Grill the skewers for about 10-12 minutes, turning occasionally, until the chicken is cooked through and the vegetables are tender.
Remove the skewers from the grill and let them rest for a few minutes before serving.
Serve the grilled chicken skewers hot and enjoy!
