Butterfly the chicken breast by slicing it horizontally to ensure thin, even cooking.
Whisk the half egg in a shallow bowl until smooth.
In a separate shallow dish, combine the almond flour, parmesan cheese, sea salt, black pepper, and dried oregano.
Dip the chicken breast into the egg wash, then press it firmly into the parmesan mixture until fully coated.
Heat the olive oil in a non-stick skillet over medium heat and sear the chicken for 5-6 minutes per side until golden brown and cooked through.
In a small saucepan, simmer the tomato puree with minced garlic over low heat for 5 minutes until aromatic.
Use a vegetable peeler to create zucchini ribbons and briefly sauté them in the chicken skillet until just tender.
Spoon the zesty tomato sauce onto a plate, top with the zucchini ribbons, and place the crispy chicken on top.
