Boil the eggs, beetroot and the prawns separately. I used small prawns, but as you will dice them, you can use bigger ones.
Once they are cook, grate the beetroot and the ginger.
Slice the red onion and keep it in cool water
Let the eggs and praens cool completely before mixing with the rest of the ingredients.
Chop, dice and mince every ingredient in each layer.
Mix all of the ingredients in each layer.
Assemble 2 slices of bread and add the first filling on top.
Do the same with the rest of the layers.
Mix the ingredients for the "frosting" and make sure all the bread is covered.
Add the decorations to your taste.
Make it vegetarian:
Change smoked salmon for sliced smoked tofu.
Swap the shrimp for regular firm tofu and chopped nori sheets.
Instead of boiled egg, use some silken tofu and, if you fancy, volcanic salt.
Make it vegan:
Change everything on top and use vegan cream cheese and mayo. Swap the crème fraîche for more cream cheese or vegan crème fraîche.
Make it Gluten-free:
Use gluten-free bread, removing the crusts.
