The Strategy
Some of the best salads are made with mayo, and they're a fabulous way to use your leftovers. Tuna, leftover chicken or deli ham all work, and you can mix in whatever you like: cornichons, bell pepper, a little vinaigrette and herbs for a Mediterranean tuna salad, or fresh thyme, almonds, grapes and a little curry with chicken. Anything you add makes your mayo salad-y thing yours.
Technique Summary
Put leftover deli ham in a food processor with white onion, celery and pickle relish and let it do all the chopping. Add mayonnaise a little at a time and mix until it's just the way you like it.
