Trim and wrap 3 trout/salmon ribbons around one of the bagel tops.
Use a vegetable peeler to shave 3 long avo strips and 3 cucumber strips and wrap around the bagel top. Add 3 slices of ginger. Repeat with the remaining bagel tops.
Mash all the remaining avo with the wasabi, if using, and lemon juice. Season with salt and pepper. Use the smashed avo as a little as ‘glue’ to stick the sesame seeds onto the bagel tops.
Spread the mashed avo onto the bottom halves of the bagels and sandwich together with the tops.
