Cook and crumble bacon. Set aside. In a clear glass bowl, add lettuce and then a generous sprinkling salt and pepper. Add spinach and another sprinkling of salt and pepper. Layer remaining ingredients in the order they appear, concentrating ingredients around the perimeter of the bowl and filling in the center with lettuce, if needed. End with the layer of peas. Combine dressing ingredients in a separate bowl and mix well. Pour over the top of the peas and spread to cover, bringing dressing all the way out to the edges of the bowl. Cover and refrigerate for up to 8 hours. Before serving, garnish the top of the salad with a little of whatever leftover ingredients you might have: egg, bacon, or a sprinkling of peas. Toss just before serving.
