  • 1 tbsp lemon juice
  • 1/4 tsp salt
  • 1/4 tsp black pepper

  7. Place another slice of cheddar cheese on top of the tuna mixture.

Notes

  • Mix hot sauce or chopped jalapeños into the tuna salad for a spicy version.
  • Swiss, mozzarella, provolone, or pepper jack can be used instead of cheddar.
