Preheat your oven to 400°F to finish cooking if needed, and heat a non-stick skillet over medium heat for the chicken.
Pat the chicken breast dry. Season lightly with salt, pepper, and any preferred spices.
In a shallow dish, beat the egg. In a separate plate, spread out the almond flour.
Dip the chicken breast first in the egg, then coat evenly in almond flour, pressing gently to adhere.
Heat a drizzle of olive oil in the skillet and cook the chicken for about 3-4 minutes per side until golden and cooked through. Alternatively, you can finish in the preheated oven for 5 minutes if thicker.
While the chicken cooks, prepare the sweet potato waffles. Peel and grate or finely mash the sweet potato until it forms a slightly chunky batter. If the mixture is too loose, you can add a tiny pinch of almond flour to bind it.
Preheat a waffle iron and lightly grease it. Spoon the sweet potato mixture onto the waffle iron and press gently to form even waffles. Cook until the waffles have a crispy exterior, about 4-5 minutes.
Plate the crispy almond-crusted chicken alongside a sweet potato waffle. Serve immediately and enjoy the blend of crunchy and soft textures as well as the balance of savory and naturally sweet flavors.
