If you marinade that chicken breast with herbs and spices, though, the taste can change considerably, and be a lot more fun. Likewise, you may get bored with eating tuna salad in your sandwiches, even though tuna is far from tasteless. But if you add a little spice when you make the tuna mix, you'll find that there's a variety of different tastes that add very little, if anything, in the amount of calories. Paprika, pepper, cayenne... the list of pepper varieties goes on. The addition of some finely diced jalapenos may make it even more interesting if you have the stomach for them. And these days, the bottles of sauce on the supermarket shelves goes far beyond steak sauce and ketchup – additions like piri-piri and teriyaki are a refreshing break from the norm.
