Method
Step 1: Marinate The Steak
- Slice the steak tenderloin very thinly. Add to a bowl with dark soy sauce, garlic powder, onion powder, salt, and black pepper. Mix well and marinate for at least 1 hour.
Step 2: Make The Spicy Mayo
- In a small bowl combine the light mayo, sriracha, and soy sauce. Mix until smooth.
Step 3: Cook The Onions
- Heat a skillet over medium heat and lightly spray with cooking spray. Add the sliced onions and cook for 6 to 8 minutes until softened and lightly caramelized.
Step 4: Cook The Steak
- Push the onions to the side and add the marinated steak to the skillet. Cook for 2 to 3 minutes, breaking apart the slices as they cook until browned and cooked through.
Step 5: Assemble The Sandwich
- Toast the ciabatta bread lightly if desired. Spread the spicy mayo onto the bread. Add the steak and onions, then top with Cheese Whiz while everything is still hot.
- Serve immediately.
