This is a recipe that people genuinely ask for - and not just because they are my in-laws and trying hard to be polite! It that constantly evolves and adapts, and each summer brings a new twist. I don't always have green onions - Vidalias work just fine. No red potatoes? Go for Russets. A little fresh thyme? Why not? It is dependable, tasty and can be adapted and stretched to feed the masses. Just add more potatoes, and more mayonnaise. Particularly fine for large picnic gatherings. Plus you can make it in the morning, and it is just right by suppertime. Charles and Camilla indulge in extra servings I have noticed. Probably because Hellmann's Mayonnaise is far superior to the salad dressings they are used to... —fineartdaily
Boil the potatoes until tender. While warm (but not still steaming hot - I have melted my fingerprints slicing too early and my life of crime may start any minute now) slice potatoes and begin to layer them in a large bowl - one layer potatoes then a handful of green onions and salt and pepper. Pour on some of the mayonnaise mixture. Repeat. Gently stir until all the potatoes are coated. You may need to add more mayonnaise mixture when you are ready to serve, as the potatoes absorb the liquid. Put on the table and stand back - the stampede might knock you down!
