  1. Switch on your sandwich toaster to heat up.

  2. Mix all your ingredients together in the bowl.

  3. Place your sandwich bread on the toaster and fill with ¼ of the mix. Repeat as required or as many as your sandwich toaster will allow at a time. Mine allows me to cook 2 at a time.

  4. Cook for a few minutes and until the cheese is melted mostly inside.

  5. Use a serrated knife to cut the sandwich in half and serve. Remember that the sandwich filling will be hot!

  6. Apply To Seriously Smug Face

Recipe Notes

  • Chop your red onion small. Click for a  really helpful link if you are unsure about how best to do this.
  • Drain your tuna well. Otherwise you will get a watery mix.
  • Make sure you add salt if you haven't used tuna in brine.
  • If you're using bread make sure it is thickly sliced as the sandwich toaster will squash it thinner or at least mine does.
  • To get ahead you can make the sandwich mix before it is required and simply cover and store in the fridge.
