I like to keep 3 ounce cups of tuna in my office for lunch and snacks. But how, you may wonder, does that single serving of tuna become a mouth-watering sandwich midday? My secret is to bring from home a small plastic container full of the tuna mix-ins du jour along with a couple pieces of bread. Then when I get hungry, I simply dump my cup of tuna into the small plastic container, stir, and spread the mixture on the bread. Super convenient, versatile, and no sogginess. Today for lunch, the mix-ins were olive oil, salt, pepper, chopped parsley and pieces of sun-dried tomato.
