A steak sandwich is a real indulgence. The humble sandwich is transformed into a meal with the addition of sliced tender and juicy meat, whether you cook it specifically for this recipe or use leftovers.

Leftover steak can be kind of tough and isn't as juicy as it was when it was first cooked. For this recipe and any leftover steak recipes, I reheat the steak slices in the microwave for just a few seconds until the slices are tender and sizzling. Assemble the sammies and eat!

All you need to serve with this recipe is a green salad tossed with sliced avocados and some grape tomatoes. Add a creamy ranch or vinaigrette salad dressing. Or you could serve a fruit salad made with seasonal fruits, drizzled with a mixture of honey, thyme leaves, and orange or lemon juice. For dessert, some brownies would be the perfect finishing touch.


  • 1 pound leftover steak (sliced)
  • 1/4 cup mayonnaise
  • 2 tablespoons mustard
  • 6 to 8 crusty sandwich rolls (sliced and toasted)
  • 8 leaves lettuce
  • 2 tomatoes (sliced)

Steps to Make It

  1. Gather the ingredients.

  2. Heat the steak, if desired, by putting it in a pan over low heat for a minute or two, or microwave for about 20 to 30 seconds for 5 to 6 slices.

  3. Assemble the sandwiches with the mayo, mustard, lettuce, sliced tomato, and the steak slices on the toasted rolls.

  4. Serve immediately and enjoy!

Recipe Variation

  • You can also spread the steak with some mayonnaise and mustard and make sandwiches with the rolls and the tomato. Wrap in foil and bake at 400 F for 12 to 18 minutes or until the sandwiches are warm. Unwrap the sandwiches during the last 2 minutes so the bread gets crisp.
