Steak time! Season your dry filets well on both sides with salt, pepper and sumac.
Take a large, heavy bottomed sauté pan over high head and add 1 tablespoon olive oil. Sear filets 2-minutes per side until nice and brown and juices start to run. Don't play with them too much!
Transfer steak to a cutting board and let rest for at 5-10 minutes.
While resting, make your dressing!
In a large bowl, whisk together Dijon mustard, lemon juice and everything bagel spice. Then slowly drizzle in olive oil while whisking until emulsified. Season with salt to taste.
Toss spinach and red onion with dressing and divide onto two plates.
Slice steak against the grain and place on greens. Top each with walnuts, a fried egg and more everything bagel spice!
