  • Flip the bread over so the buttered side is against the pan. Put a scoop of tuna salad on the unbuttered side of 4 pieces of bread. Spread the tuna out evenly.

  • Top with the remaining bread, being sure the buttered side is on the outside.

  • Bake the sandwiches for about 10 minutes until the bread is golden and the cheese is melted. There should be no need to flip the sandwiches, they should be golden on the bottom side. Note: if you like more browning you can switch to broil for the last minute or so, but watch carefully, the bread can burn quickly.

Notes

 
  • For open faced tuna melts, omit the second piece of bread and add an extra slice of cheese.
