Prepare the dressing by whisking the olive oil, lemon juice, zest, salt, mustard and seasonings together. Clean and tear the salad greens into small bite size pieces and use to line the serving platter. Amounts of remaining ingredients are flexible, depending on the number of people being served. To serve four, use ¾ to 1 cup of each item. Spoon each ingredient onto the platter in a neat line, being sure to alternate colors. When ready to serve, drizzle with dressing.
