After playing around with this for a while I've discovered this is the best method.
This is incredibly tasty and almost anyone can eat it since EVERYTHING can be changed for something else!
I love adding tomatoes or sweetcorn to add a little bit extra.
1
Turn on your grill on a medium to high setting.
Toast 2 slices of bread (I use the toaster cos its quicker.
2
Layer your tuna on one of the slices of toast. The thicker the tuna, the longer it will take to warm through.
3
Put the tuna-toast under the grill. Leave the other toast slice where it is for now.
Grill until the tuna is warm through.
4
Use this time to slice your cheese and whatever else you're putting in. I'm just using Applewood Smoked cheese this time. 4 slices is plenty for my bread.
5
When the tuna is warm, take it out of the grill and lay the cheese on top.
6
Return to the grill until the cheese has started to melt.
7
Place the other slice of toast on top in the grill to warm it through.
Careful not to burn yourself!!
8
Take the sandwich out, cut and enjoy!
