  4. Cook Steak: Preheat grill or skillet, cook marinated steak for about 5-7 minutes per side.
  5. Make Garlic Dill Spread: Sauté minced garlic, then mix with mayo, sour cream, and fresh dill.
  6. Assemble the Sandwich: Slice the baguette, spread garlic dill mixture, layer steak, caramelized onions, mushrooms, cheese, and arugula.
