I don't know if it's in the cookbook, but it's here on the thread...I like the tuna burgers. Mix 4oz of tuna (actually a little more because you lose some of the weight after they're cooked) with an egg white and melba toast. Put in whatever flavors you like in seasoning. I used Mrs. Dash lemon pepper, garlic, and red pepper flakes (most of this comes from the recipe on the recipe thread but I add a little more to it). I sometimes will put a little bit of Dijonnaise in there too. Then just make them into patties and throw them in the pan and cook them like a hamburger. They're quite tasty!
What I did the other night was sautee some spinach in with them and made a has out of it. Now you have all your necessary foods in one dish. But if you are sauteeing fresh spinach, do that first and then weigh it (to make sure it's 4oz) and then throw it in with the tuna.
