Preheat your oven to 400°F. Line a baking sheet with parchment paper.
Season the chicken breasts with salt and pepper.
Set up a breading station: Place the flour in one shallow dish, whisk the eggs in another, and combine the panko breadcrumbs, garlic powder, and paprika in a third dish.
Dredge each chicken breast in flour, shaking off the excess. Dip into the beaten eggs, then coat thoroughly with the panko mixture.
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the breaded chicken breasts and cook for about 4-5 minutes on each side, or until golden brown and cooked through. Transfer to the baking sheet and keep warm in the oven.
In the same skillet, add 1 tablespoon of olive oil and the sliced zucchini. Cook for about 5-7 minutes, stirring occasionally, until the zucchini is blistered and tender. Season with salt and pepper.
For the herby green sauce, combine the parsley, basil, chives, olive oil, lemon juice, minced garlic, salt, and pepper in a food processor. Blend until smooth. Adjust seasoning as needed.
Serve the crispy chicken topped with blistered zucchini and drizzled with herby green sauce.
