When adding avocado to a #4 sandwich, where is it placed?

The correct placement of avocado when adding it to a #4 sandwich is on the turkey. This positioning is important because it allows the rich, creamy texture of the avocado to complement the flavor and moisture of the turkey directly. Placing it in the center or on another ingredient alters the distribution of flavors, which can affect the overall taste experience. Additionally, putting avocado directly on the turkey ensures that each bite has a balanced mix of the sandwich's key ingredients, enhancing the overall quality and satisfaction of the meal. The strategic layering also helps to keep the ingredients fresh, preventing the avocado from being overwhelmed by drier components like the bread or lettuce.
