Fat, carbs, alcohol, whatever...I need to be aware of total calories, so I'm a canned-tuna maven.

I'm in London...recently I encountered a Chinese vegetable called "Garlic Scape," which turns out to be divine when chopped very small into a tuna salad. It's like a cross between scallions and chives; about the same size as a scallion, but without the "dragon breath." The effect on the breath is comparable to a large amount of chives.

Not sure how helpful this is, but it's one way I've attempted to relieve my tuna boredom.
