As a kid, I loved tuna sandwiches so much, I even convinced my grandmother to try mixing the fish with a little caramel spread on toast. Not surprisingly, that concoction put the kibosh on further experiments with canned fish, but I still crave a tuna sandwich now and then. If you, too, want a little tuna but have trouble keeping track of which cans can be purchased with a clear conscience, you’ll want to download Greenpeace’s new sustainable tuna guide app. It ranks almost 100 products, telling you which options sink or swim.
