RE: John West's Tuna with a twist?
Tuna is a decent choice as it's so versatile and can be eaten cold
I like Tin of tuna (drained)
Then add a little extra virgin oil with salt,pepper,vinegar (lots for me), lemon/lime juice, 2 or 3 spoons of natural yogurt (instead of mayo)
Add chopped up peppers/cucumber/tomato's etc,etc add sweet corn??
Then add this to half a bag a conchigliette (tiny pasta shells)
Great meal can be prepared and stored well in advance
Hope this helps
