Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a shallow bowl, whisk the egg until smooth. In a separate bowl, combine the almond flour, parmesan cheese, oregano, garlic powder, sea salt, and black pepper.
Dip the chicken breast into the egg wash, then coat it thoroughly with the almond-parmesan mixture, pressing firmly so the breading adheres.
Place the chicken on the baking sheet and bake for 18-22 minutes until the internal temperature reaches 165°F and the crust is golden brown.
While the chicken is baking, mince the garlic clove and sauté it in olive oil over medium heat for 1 minute until fragrant.
Add the tomato puree to the pan and simmer for 5 minutes, then briefly toss in the zucchini noodles for 2 minutes until just tender.
Place the zucchini noodles on a plate, top with the zesty tomato sauce, and finish with the crispy baked chicken breast.
