Place the beef cutlets between two sheets of parchment paper and pound with a meat mallet until they are an even 1/4 inch thickness.
In a shallow bowl, whisk the egg white until slightly frothy.
In a second shallow bowl, combine the almond flour, nutritional yeast, dried oregano, garlic powder, sea salt, and black pepper.
Dip each beef cutlet into the egg white, allowing the excess to drip off, then dredge thoroughly in the almond flour mixture, pressing to adhere.
Heat 2 teaspoons of the olive oil in a large non-stick skillet over medium-high heat.
Add the beef to the skillet and sear for 3 minutes per side until the crust is golden brown and the beef is cooked through.
While the beef cooks, whisk the remaining 1 teaspoon of olive oil with the lemon juice in a medium bowl.
Add the baby arugula to the bowl and toss gently to coat with the dressing.
Transfer the beef to a plate, top with the dressed arugula salad, and finish with the shaved parmesan cheese.
