This Philly Grilled Cheese Sandwich gives steak-night leftovers an encore. Tender steak and grilled veggies sandwiched between melted cheese and crispy, toasted bread, that’s going to rock your lunches world.


  • 4 slices thick bread, such as Italian or rustic bread
  • 1 tablespoon butter, for grilling
  • 1/4 cup finely diced onion and pepper mix, thawed
  • 4 slices American cheese
  • 1 cup leftover grilled steak or 4 slices deli-cut roast beef


Butter one side of each bread slice and set aside.

Melt the butter on a griddle or skillet over medium-high heat. Add the onion and pepper mix, sauté for 3 to 4 minutes or until onions have softened. Add the leftover steak or roast beef onto the griddle or skillet and cook until warmed through. Remove from heat.

Onto the griddle or skillet, place the bread slices butter side down and grill, until golden brown. Remove from heat and set aside.

Once bread is ready, spread the onion and beef mixture on the griddle, separate into 2 sections and top with each section with 2 cheese slices. Once the cheese is melted, transfer each section onto a toasted bread slice, assemble the sandwiches.

Serve immediately, or, to pack inside a lunchbox, wait for the sandwich to cool down to room temperature prior to slicing in half and packing inside the lunchbox.
