Prep all the marinade ingredients in a gallon-size plastic bag, seal the bag, then use your hands to combine all the ingredients. I like to take the bag in the palm of my hands from both sides and smash everything together, then shake the bag until it's well combined.
Place the steak in the marindade and reseal the bag. Place the bag in the refrigerator for at least 1 hour and up to 24 hours.
Prepare your salsa gremolata by chopping and mincing all the ingredients. Then toss them in a bowl.
Zest your lemon overtop the bowl and then squeeze the lemon juice over that.
Pour the olive oil into the bowl then season with salt and pepper.
Use a fork to combine everything, then store in the fridge until you're ready to assemble your steak salads.
Prepare your balsamic vinaigrette by adding all the ingredients to a small mason jar. Put the lid on the jar and vigorously shake until fully combined. Set aside until you're ready to dress the arugula.
Prepare your grill by heating it over medium-high heat (depending on the weather - if it's cold you'll cook it higher than if it's warm).
Add your asparagus and cook until just slightly softened and charred.
Place the steak on the grill using tongs and let it cook for about 2-3 minutes on each side. Continue to rotate the steak every 2-3 minutes until the steak has finished cooking to your desired level of doneness.
Let your steak rest for at least 5-10 minutes before slicing it. *see below for cast-iron steak instructions.
While the steak is resting dress and assemble your salad. First, drizzle your desired amount of the balsamic vinaigrette on the arugula (add less than you think - you can always add more but you can't take away).
Then, top the arugula with the tomatoes, grilled asparagus and smoked blue cheese.
Slice your steak against the grain into thin strips and top your arugula salad with your steak strips.
Drizzle the salsa gremolata overtop the steak and serve the salad.
