Preheat your oven to 425°F for the sweet potato wedges.
Slice the sweet potato into wedges, toss them in a teaspoon of olive oil, and season with a pinch of salt, pepper, and a sprinkle of dried oregano.
Spread the wedges on a baking sheet in a single layer and roast for 20-25 minutes, turning halfway, until crispy and tender.
While the wedges are roasting, pound the chicken breast slightly for even cooking.
In a shallow bowl, whisk the egg white with garlic powder, dried oregano, salt, and pepper.
Dip the chicken breast in the egg white mixture, ensuring it is well-coated with the herbs.
Heat a non-stick skillet over medium-high heat and cook the chicken breast for about 5-6 minutes per side, or until fully cooked and lightly charred on the outside.
Lightly toast the whole wheat bun in the skillet for additional texture if desired.
Assemble the burger by placing the herb-crusted chicken on the bottom bun, topping with your preferred fresh veggies if desired, and then capping with the top bun.
Serve the burger alongside the crispy sweet potato wedges for a well-balanced meal.
