mayonnaise, mustard, a little salsa and or relish. Add your choice of seasoning. I put chipotle seasoning on chicken salad and seafood seasoning on tuna. I also do the egg salad.
I know...Need something to spice it up a bit, but salsa doesn't work with my sleeve and eating too many carbs is not good also. I stopped eating tuna for a bit because I got bored and chicken can be too dry for me. Good Luck!
