Tuna Melt with Tomato Soup

Instructions

1. 1

   Prepare the tuna salad

   • In a medium bowl, use a fork to flake the thoroughly drained tuna.
   • Add the mayonnaise, finely chopped celery, finely chopped red onion, lemon juice, Dijon mustard, salt, and pepper.
   • Stir until all ingredients are well combined, but be careful not to overmix.
2. 2

   Assemble the sandwiches

   • Lay out the 8 slices of bread on a clean work surface.
   • Spread the softened butter evenly on one side of each slice of bread.
   • Flip 4 of the slices over so the buttered side is down.
   • On the unbuttered side of these 4 slices, layer one slice of cheese, a quarter of the tuna salad mixture, and a second slice of cheese.
   • Place the remaining 4 slices of bread on top, with the buttered side facing up.
3. 3

   Grill the tuna melts

   • Heat a large non-stick skillet or griddle over medium-low heat.
   • Carefully place 1 or 2 sandwiches in the skillet, ensuring not to overcrowd it.
   • Grill for 4-5 minutes on the first side, until the bread is a deep golden brown and crispy.
   • Flip the sandwiches carefully and grill for another 3-4 minutes on the other side, until the cheese is completely melted.
   • Repeat the process with the remaining sandwiches.

   Serve
