Preheat your oven to 425°F and line a large baking sheet with parchment paper.
Slice the zucchini into thin spears, roughly 1/2 inch thick, and pat them thoroughly dry with a paper towel to ensure maximum crispiness.
In a shallow bowl, whisk the egg white until slightly frothy. In a second bowl, combine the almond flour, parmesan cheese, and half of the garlic powder, onion powder, salt, and pepper.
Dip each zucchini spear into the egg white, then roll it in the almond flour mixture until evenly coated, and place on the prepared baking sheet.
Rub the chicken breast with olive oil, lemon juice, dried oregano, and the remaining spices, then place it on the same baking sheet next to the zucchini.
Bake for 18 to 22 minutes, flipping the zucchini halfway through, until the chicken reaches an internal temperature of 165°F and the zucchini fries are golden brown.
Serve the crispy zucchini fries with a side of plain Greek yogurt for dipping and the sliced herb chicken.
