As usual a prosaic recipe
for tuna salad;
I found that two very strong flavors sort of cancel each other out.

I mix 2 tbl spoons of strong horseradish with four cans of albacore tuna and mayo equivalent to 1/2 the mixture. I add diced and equal amounts of ; thick onion slice, colored peppers and 1/2 dill or half sour pickle equivalent to the whole mixture. I add a teaspoon of Coleman mustard or a bit more of another kind of mustard. Mix well. The taste is veggie dominant and the tuna is the smooth almost bland protein. Experiment with a seasoning like Peruvian chicken or spiracha for a kick.
Tricking the pallette is even more dynamic by eating Miracle Fruit followed by drinking lemon juice which then tastes sweet with no sourness whatsoever.
