• 4 lbs white potatoes, diced
• 1 cup celery, diced
• 1 cup dill pickle, diced (real dills)
• 1 cup pepperoni, diced
• 1 (6 ounce) can pitted black olives, drained and diced

1. Peel and wash potatoes; cook in boiling water until just fork tender (do not over cook).
2. Cool and dice approximately 1/2 x 1/2-inch; combine with all other diced items (onions, pickles, pepperoni, cheeses, celery and black olives). Fold all of these ingredients gently with 1/2 cup of mayonnaise until mixed.
3. Refrigerate for at least a couple of hours, overnight is even better (this is important).
4. Add all spices and the rest of mayonnaise and minced garlic; gently fold until mixed. Refrigerate 30 minutes to 1 hour before serving.
