Serve on a bed of chopped lettuce with corn chips on the side (try jalapeño-flavoured). Also great with toasted sourdough or crackers! Regular mayonnaise works well in this recipe if you don’t enjoy the flavour of wasabi. Alternatively, try half and half, or use regular mayonnaise and add a small amount of wasabi paste. This tuna salad mix keeps well in the fridge for 2 days - the flavour is even better after 24 hours. Add the crispy onions just before serving.
