Cut the white rubber-like tendon off the tenderloins. (This will otherwise ruin the texture)

Marinate the tenderloins in the beer for 2-4 hours.

Preheat oven to 400º

Combine soy sauce, sesame oil, vinegar, sesame seeds, ginger, 1 t onion powder, lemon peel seasoning, white pepper, and garlic in a small mixing bowl. Whisk together. (Even better when done the night before!)

Drain tenderloins and discard marinade. Pat dry with paper towels.

Drizzle tenderloins with enough oil to coat.

Season with 1/4 t onion powder, garlic powder, coriander, and salt.

Lay tenders on a baking tray lined with parchment paper.

Cook for approximately 12 minutes, or until thermometer reaches 165°.
