I messed up and replaced my broken breville triangle toasty maker with a std flat plate one that I thought would be more versatile and could do paninis etc. It is versatile but I miss those pockets of molten cheese you get when the triangle types fuse the bread together along the seam.
cheddar cheese and ham with onion and tomato is great. I used to divide a dairy lea triangle between each side as well for a special treat. try it.
my nan used to make me burger and onion toasties when I was a kid. just a std birds eye burger (pre cooked perhaps) with onions in it as well. Lovely with brown sauce.
Also I was telling my wife last night about the garage at Bonvilston on the A48 between Culverhouse Cross and Cowbridge. We used to sell xmas trees up the road and the garage was a top spot as they did pre cooked toasties of all flavours just piled up on the shelf in a paper bag if I remember. They were great and 30 secs in the microwave and bobs your uncle. Saw Tom Jones there once as well, can’t remember if he bought a toasty though…
