I mix in rice and tiny bits of spinach or broccoli flower tips in with tuna and mayo. Because tuna has such a overpowering flavor, the possibilites for what you can hide in this kind of sandwich is immense. Also, I like to cut down on the amount of tuna I serve, but not completely eliminate it; especially since it’s so useful to my ulterior motive! I warm up rice and frozen organic spinach before mixing in with the basic tuna mix. What could be more quick & easy!?
