Upgrade your boring lunchtime sandwich with this easy Tuna and Cheese Melt Panini recipe.
Homemade tuna mayo with red onions, a splash of Sherry or Balsamic vinegar and a pinch of paprika. Sandwiched between cheese slices inside a panini roll.

Toasted in a George Foreman or Optigrill until the roll is perfectly crisp and the cheese is deliciously melted into the onion and tuna mayonnaise mixture! Best lunch ever!

How to make tuna mayo and onion sandwich filler?
Simply mix together a tin of tuna with ½ a red onion (finely diced), 3 tablespoon of mayo, a pinch of paprika, with a splash of sherry / balsamic vinegar.
This will make enough to serve 2 in panini rolls.
How to make Tuna and Cheese Panini?
Spread some mayo on both sides of panini roll, add a slice of cheese on the bottom followed by the tuna mayo mixture, then another cheese slice.
Finally, finish with the top half of panini.
Obviously, if you wanted it can be eaten like this as a cold panini roll.
However, we like to make it into a heavenly cheese and tuna melt.
How to make toasted Tuna and Cheese Melt Panini?
We use a Tefal Opti Grill, however, a George Foreman grill or similar will work the same.
Spray both the top & bottom preheated grill plates with some spray oil, we used Frylight.
Place the panini on the grill plate & shut lid gently on top. Set timer for 4 minutes.
Check to see if the panini roll is crisp and the cheese has melted.
Serve up with a side salad and crisps or chunky air fryer chips.
The cheese melts so beautifully into the tuna mayo and onion mix. You will undoubtedly savour every mouthful!
