One of the best things about leftover ham is making this ham salad sandwich spread. Make it using a meat grinder or food processor - grind leftover ham, pickle, onion, and mix it all up with real mayo. Simply delicious!!
Grind ham, pickles, and onion in a meat grinder or food processor into a medium-size bowl. 
After grinding, combine the ingredients adding enough real mayo to moisten and make a spreadable consistency.
Serve immediately or refrigerate until needed.
 If using a food processor, pulse to chop the ham. You want it reasonably fine chopped but not a paste consistency.*If you need to be gluten-free and have a ham brand you’ve eaten and liked that hasn’t given you a reaction, then go ahead and stick with that.
