Preheat your oven to 400°F. Prepare a baking sheet by lightly greasing it with olive oil.
For the chicken: Pat the chicken breast dry. Season with salt, pepper, and garlic powder.
In a shallow dish, beat the egg. In another dish, place the almond flour. Dip the chicken into the egg, allowing any excess to drip off, then dredge in almond flour until evenly coated.
Heat a non-stick skillet over medium heat with a small drizzle of olive oil. Sear the chicken for about 2-3 minutes per side until it begins to get crispy.
Transfer the chicken to the baking sheet and finish cooking in the preheated oven for 10-12 minutes until fully cooked and the almond crust is crispy.
For the sweet potato waffles: Peel and cube the sweet potato. Boil or steam until tender, about 10-12 minutes. Drain and mash until smooth.
Preheat your waffle iron. If desired, season the mashed sweet potato lightly with salt and pepper. Spoon the mixture into the waffle iron and cook for 4-6 minutes until golden and slightly crispy on the outside.
Plate the crispy almond-crusted chicken alongside the golden sweet potato waffles. Garnish with a sprinkle of garlic powder or additional herbs if desired, and serve warm.
