Preheat the oven to 400°F.
In a shallow bowl, whisk the egg with a pinch of salt and pepper.
In another plate, combine almond flour, dried thyme, dried rosemary, garlic powder, and a little extra salt and pepper.
Dip the chicken breast into the egg mixture, ensuring it's fully coated, then dredge in the almond flour mixture, patting gently to adhere.
Place the coated chicken on a lightly greased baking sheet or rack.
In a mixing bowl, toss the cauliflower florets with olive oil, salt, pepper, and a pinch of dried herbs if desired.
Spread the cauliflower evenly on a separate baking sheet.
Bake the chicken for 20-25 minutes or until the internal temperature reaches 165°F, and bake the cauliflower for 15-20 minutes until tender and slightly caramelized.
Serve the crispy almond-crusted chicken alongside the herb-roasted cauliflower while warm.
