Bold yet rich flavor from gochujang and a bit of sweetness make this a delicious and easy steak meal. I like to serve this with a finely shredded cabbage seasoned with vinegar and sesame. Finally, a garnish of green onion brightens everything up.
Combine all steak ingredients except the avocado oil in a large bowl and stir to coat evenly. Set aside to marinate for 15 minutes at room temperature, or up to overnight.
Toss the cabbage with vinegar, monk fruit, and sesame oil. Season to taste with salt.
Heat 1 teaspoon avocado oil in a hot pan over medium-high heat. Add the beef and cook until browned on all sides cooked to your liking, about 7 minutes for medium rare (125ºF).
Serve over a bed of cabbage with the green onions for garnish.
