Bread is a great example of a processed food. Depending on the bread you are extracting out fiber (enriching), adding in elements to modify texture (yeast or baking soda/powder), restoring nutrients (B vitamins), oils, enhancing shelf life with enzymes, vinegars (acetic acid), pectins, securing in freezer burn resistant plastics. The level of processing is up to you and your preferences, same thing for vegans.
