Every time I take out my recipe to make this, my mouth waters in anticipation. By tossing the diced warm potatoes with the lemon, garlic and olive oil mixture, the flavors really get into the potatoes and moistens them. This allows you to use less mayonnaise and eliminates the need for bacon fat. The pastrami more than makes up for the traditional bacon flavor. Cooking time does not include chilling time. This is best made the day before serving so the flavors can meld.
