In a bowl, mix olive oil, soy sauce, honey, minced garlic, paprika, salt, and black pepper. Add chicken breasts and marinate for at least 30 minutes.

Preheat the Blackstone griddle over medium-high heat. Lightly oil the surface.

Place the marinated chicken breasts on the griddle. Cook for about 6-7 minutes on each side or until the internal temperature reaches 165°F (75°C).

In the last 5 minutes of cooking, add the sliced bell peppers, zucchini, and red onion to the griddle. Sauté until tender.

Remove chicken and vegetables from the griddle. Let the chicken rest for a few minutes before slicing. Serve with vegetables.
