Run a potato peeler along the side of a cucumber to create long, thin ribbons. Thinly slice the red onion and toss together with the cucumber.
Add the white wine vinegar and chopped dill, and continue to mix until thoroughly coated.
Remove crusts from the slices of bread. Cut lengthways down the centre of the slice, then cut into quarters. Crisp up quickly under a hot grill.
Lay the salmon terrine out onto a plate, and assemble the cucumber salad and melba toasts. Serve with the lemon wedges for squeezing.
Notes
If you have the time or the inclination, try whipping up your own salmon terrine. Our hot smoked salmon portions whipped with cream cheese and seasoning make a delicious filling, perfect when wrapped with our smoked salmon slices.
