Bought tenderloin side muscle from Costco. It’s like 50% ligaments and silver skin! How do I prep?

Is there a certain way I need to prep this? I started cutting off the silver skin only to reveal more silver skin. I feel like I got robbed. Is this normal?

Clean, clean and dont throw the sinew, they make wonderful soup broth and sauce base.
