Preheat your oven to 400°F (200°C) for the herb sticks and preheat a grill or grill pan to medium-high heat.
Cut the chicken breast, red bell pepper, zucchini, and red onion into uniform 1-inch cubes for even cooking.
In a small bowl, whisk together the olive oil, lemon juice, dried oregano, garlic powder, sea salt, and black pepper to create a marinade.
Place the chicken and vegetable cubes in a large bowl, pour the marinade over them, and toss until every piece is well-coated.
Thread the marinated chicken and vegetables onto skewers, alternating colors for a beautiful presentation.
Divide the whole wheat dough into two pieces, roll them into thin sticks, and press the finely chopped fresh rosemary into the surface.
Bake the herb sticks on a parchment-lined tray for 10-12 minutes until they are golden brown and firm.
While the sticks bake, grill the skewers for 10-12 minutes, rotating every few minutes until the chicken is cooked through and the vegetables have a light char.
Remove the skewers and herb sticks from heat and serve immediately while hot.
