For each sandwich, toast two slices of bread. While the bread is toasting, slice your tomato and avocado

Slather as much (or little) mayonnaise as you like on one side of each slice of toasted bread. Add a layer of sliced avocado Add a layer of lettuce and a layer of sliced tomatoes. Sprinkle a little salt over the tomatoes too.

Top with the second slice of toasted bread. Cut the sandwich in half if you want, to make it easier to eat. Enjoy!
