This filling salad will also work really well with tinned tuna. We suggest using tuna in springwater because the dressing itself is so flavoursome. It’s best to use tuna that is closer to its natural flavour. You can pick up hot-smoked trout at the supermarket. It comes shrink-wrapped and in a fillet. Here we have used hot-smoked river trout, but you can also use rainbow trout, or even hotsmoked salmon. They all work beautifully in this tasty recipe.
