1 hot-smoked salmon fillet, flaked into large chunks
small handful rocket
In a small bowl, mix together the mayonnaise, lemon zest and juice, and some seasoning. Toast the bread, then spread 2 slices with the lemon mayo. Top the first slice with the radishes and avocado, then top with the second slice, followed by the salmon and a bit of rocket. Top with the remaining slice of toast and secure with cocktail sticks, if you like. Halve the sandwich and serve with the remaining rocket on the side.
