Steps
1. In a bowl, combine olive oil, paprika, garlic powder, salt, and pepper.
2. Add the chicken and beef to the marinade, ensuring all pieces are well coated. Let it marinate for at least 15 minutes.
3. Preheat a grill or grill pan over medium-high heat.
4. Thread the marinated meats and bell peppers onto skewers alternately.
5. Grill the skewers for about 10-12 minutes, turning occasionally, until the meats are cooked through and slightly charred.
6. Serve the skewers on a plate, garnished with fresh parsley, and alongside the whole wheat pita.
