Remove onion mixture from the heat and, in a blender or food processor fitted with a steel blade, blend together with the crackers, white cheese, evaporated milk, and salt, adding just enough vegetable oil to give the mixture a smooth creamy consistency. Add the juice of 1/2 key lime and blend for a few seconds more. Adjust seasoning to taste, adding more salt if necessary. Let sauce cool to room temperature or chill in the fridge. To serve, pour the sauce over sliced cold boiled potatoes and garnish with boiled egg slices, olives, cooked corn kernals and lettuce leaves.
