Turn a couple cans of tuna into a zesty tuna burger with this quick recipe. If you can't find good whole-wheat hamburger buns, whole-wheat English muffins are a great substitute. The burger mixture might seem a little soft going into the pan, but once the first side is cooked, you'll be able to flip them easily. Serve with steamed broccoli or sweet potato fries.
