Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
Flatten the chicken breast to an even thickness by gently pounding it between two sheets of plastic wrap.
Season the chicken breast with salt and pepper on both sides.
In a shallow bowl, whisk the egg until fully combined.
Place the almond flour in a separate shallow dish.
Dip the chicken breast first into the egg, ensuring it is fully coated, then dredge in the almond flour until a light, even coating forms.
Place the coated chicken on the prepared baking sheet and bake in the preheated oven for 20-25 minutes, until the chicken is cooked through and the coating is crisp.
While the chicken is baking, prepare the sticky sauce. In a small bowl, combine the honey, sriracha, and rice vinegar. Mix well until smooth.
Once the chicken is done, drizzle the sticky sauce evenly over the crispy chicken, or serve it on the side for dipping.
Garnish with a sprinkle of pepper and serve immediately.
