Finely chop the shrimp and mix into a dough.
Shape the dough into a round patty, then coat in flour, beaten egg, and breadcrumbs, in that order.
Add enough oil to a pan and deep-fry the shrimp cutlet until crispy.
Spread sauce (tartar or your preferred sauce) on the sandwich bread.
Place the fried shrimp cutlet and lettuce onto the bread to make a sandwich.
Cut into convenient pieces and arrange on a plate.
