Preheat your oven to 400°F.
Begin by preparing the chicken: Pat the chicken breast dry and season lightly with salt, pepper, and a pinch of garlic powder.
In a shallow dish, combine the almond flour with a pinch of garlic powder and additional salt and pepper. In another bowl, beat the egg.
Dip the chicken breast first into the beaten egg, ensuring it is fully coated, then dredge thoroughly in the almond flour mixture so that it forms a consistent crust.
Heat a non-stick skillet over medium heat with a drizzle of olive oil. Sear the chicken breast on both sides until the almond coating is golden (about 2-3 minutes per side).
Transfer the seared chicken to a baking sheet and finish cooking in the oven for an additional 10 minutes, or until the chicken reaches an internal temperature of 165°F.
Meanwhile, prepare the herb-roasted cauliflower biscuits: In a bowl, combine the riced cauliflower, chopped fresh parsley, garlic powder, salt, and pepper. Mix well.
Place small rounds of the cauliflower mixture onto a greased baking tray, pressing gently to form biscuit shapes. Drizzle lightly with olive oil if desired.
Bake the biscuits in the same oven for about 12-15 minutes until they are set and lightly golden on the edges.
Plate the almond-crusted chicken alongside a couple of the herb-roasted cauliflower biscuits and serve immediately.
