I found this and thought it was a really cool idea. I love a bit of trashy food and the plastic cheese in this really makes it lovely and melty. I did try and make it a bit healthy by adding mushrooms and tomatoes though!
Egg, Mushroom and Cheese Sandwich (from A Cup of Jo)
1 English muffin or two slices bread or a bun
1 to 2 tsp butter or oil
salt and pepper
handful mushrooms, sliced
1 slice of plastic cheese
Heat some butter and oil in a frying pan and cook the mushrooms until golden and tender.
Beat the egg with ½ tsp water until just blended, season.
Melt the butter in a frying pan. Pour in the eggs and roll them around so they cover the pan, as a thin crepe would.
Put the square of cheese in the middle and place the mushrooms on top. cook until the egg is cooked, about 1-2 mins.
Fold the part of the egg closest to you over the cheese. Repeat this on the three remaining "sides," forming a small square.
Leave the folded egg-and-cheese in the centre of the frying pan to cook for another 30 secs, then slide onto you muffin or toast. Top the sandwich with the tomatoes and other half of the bread and eat it at once.
