Slice the yellow potato into 1/4-inch thick rounds.
Place the chicken breast between two sheets of parchment paper and pound with a meat mallet until it is an even 1/2-inch thickness.
In a shallow bowl, whisk the egg. In a second shallow bowl, combine the breadcrumbs, garlic powder, and paprika.
Season the chicken breast on both sides with sea salt and black pepper.
Heat 0.25 tablespoons of avocado oil in a large non-stick skillet over medium heat. Add the potato rounds in a single layer and cook for 5-7 minutes per side until tender and sizzled. Remove and set aside.
Wipe the skillet and add the remaining 0.5 tablespoons of avocado oil over medium-high heat.
Dip the chicken into the egg wash, then press into the breadcrumb mixture until fully coated.
Place the chicken in the hot skillet and cook for 3-4 minutes per side until the crust is golden brown and the chicken is cooked through.
Serve the chicken schnitzel with the potatoes and a fresh lemon wedge for squeezing.
