A delicious and easy-to-make sandwich, filled with tender beef, caramelized onions, and melted cheese, perfect for busy weeknights.
For leftovers, store the beef mixture in an airtight container in the refrigerator for up to 3 days or freeze for up to 2 months. Reheat by simmering in a skillet with a splash of beef broth.
