Preheat your oven to 425°F and lightly grease a large rimmed baking sheet with the avocado oil.
Slice the zucchini into 3-inch long spears and cut the chicken breast into thin, even strips.
In a shallow bowl, whisk the egg until smooth. In a separate shallow bowl, combine the almond flour, parmesan cheese, garlic powder, onion powder, sea salt, and black pepper.
Dip each chicken strip and zucchini spear into the egg wash, allowing excess to drip off, then coat thoroughly in the almond-parmesan mixture.
Place the coated chicken and zucchini in a single layer on the prepared baking sheet, ensuring they do not touch to allow for maximum air circulation.
Bake for 18-20 minutes, flipping halfway through, until the coating is deeply golden and the chicken is cooked through to an internal temperature of 165°F.
