After-work healthy snack ideas. My fave: Salsa-fied Tuna Stacks - Here's a little three-ingredient recipe I dreamt up and fell in love with. Just mix 1/4 cup flaked albacore tuna (packed in water and then drained) with about 3 tbsp. salsa. Divide the mixture between two rice cakes (I like the lightly salted ones), and CHOMP into your open-faced treat. The whole thing has only about 150 calories!
