½ tablespoon EACH: grainy mustard, dijon mustard, and balsamic vinegar
2 tablespoons olive oil
A pinch of salt and pepper
Take the steak out of your fridge and evenly coat both sides with the salt and pepper. Add all the salad ingredients to a salad bowl.
Heat a cast iron or heavy-bottomed pan over high heat. Drizzle the avocado oil over both sides of the steak. When the pan starts to smoke, add the steak and let it cook undisturbed for 3-4 minutes. Flip the steak over and let it cook for 3-4 minutes more*. Transfer the steak to a cutting board and let it rest.
While the steak is resting, whisk the salad dressing ingredients in a small bowl. Thin the dressing with up to a tablespoon of water, as needed. Pour the dressing over the salad and toss.
Thinly slice the steak across the grain and serve it over the salad. Add Blue Cheese or olives if desired.
