Spinach salad is as simple to make as it is good to eat.
Remove the bacon from the skillet, reserving the drippings. Next, add the vinegar, water, and sugar to the skillet and bring to a boil. Meanwhile, beat the egg. When the contents in the skillet begin to boil, remove them from the heat and add one-quarter of the beaten egg, stirring constantly so you don't wind up with scrambled eggs. Add the remaining egg, and continue stirring constantly until the mixture is well blended.
