Cook 8 medium red potatoes until fork tender. Set aside to cool enough to peel, but do not let potatoes get cold as they will absorb seasoning better when warm.
Dice slightly cooled potatoes into bite-sized pieces and place into a bowl.
Add to the potatoes 1 medium onion, 1 tbsp salt, 1 tsp garlic salt, 1 tsp celery seed, and 1 tsp white pepper.
Peel 10 hard boiled eggs, reserving 2 for garnish. Chop the remaining 8 eggs and add to the potato mixture.
Add ¾ c sweet pepper relish and mix.
Stir in 1 c salad dressing and if desired mustard.
Garnish with the remaining 2 sliced eggs, paprika, and 1 small jar pimentos.
Notes
We'll usually sub out celery salt and cut salt out completely for this recipe, and for mustard we do a mix of yellow and Dijon mustard- Z & B
