Cannot live without tuna. I absolutely love the stuff!
When bulking (for lunch), I used to smash down 1 x 425g tin (with olive oil), with 1/2 a chopped cucumber, 1 x chopped tomato, 1/2 an avocado with dash of Paul Newman's 'light' Balsamic dressing. I still eat the same thing every day although now I have restricted myself to only 1/2 a can.
IMO, Solmare is the best tasting by a long shot. About the only thing that can turn me off tuna is buying the Coles shit. Worst. tuna. period! The Coles tuna is low in protein compared to more expensive brands too.
