For those of us who like the crunch but hate the onions and radishes:

1 can of solid white albacore tuna (Bumblebee rocks)
about 4 tbsp. mayonnaise
1 tbsp. stoneground mustard
1/3 c. diced dill pickles
1/2 c. sliced black olives
1/2 c. chopped celery
(optional) - 1/2 c. chopped canned pineapple
1 tsp garlic powder
1/2 tsp basil
salt and pepper to taste

Mix it all together, and add more mayo or mustard to make sure the mixture is just creamy enough to spread. This goes best on toast or crackers.
