Cut the avocado into half and slice length ways. (the other half save for later)
Slice the lettuce, ready for later
Add the mayonnaise on one slice of bread and on the other add the mustard, and make sure which way you are going to cut it, later.
Fist add the Lettuce, red cabbage, avocado then 1tbsp mayonnaise on the avocado.(don't forget which way you will cut) Make sure your avocado is laid the right way.
Then add the cheese laid in the same direction as the avocado, then finally add the carrot.
Put the other slice of bread on top, then place the backing sheet under the bread and begin to fold. Firstly fold over the top and bottom so they meet in the middle. Fold the middle section in on itself, as the photo shows, until tight.
Next fold the outer edges into triangle shapes, as you would when wrapping a gift. Then fold these under the sandwich.
Then you will cut across the sandwich to get the best effect, you must remember which way you wrapped it.
You will get a wonderful surprise when you cut through and see the sandwich. Enjoy your meal.
