I don't get why people put tomatoes or lettuce on burgers. They add no real flavor. I do pickles. And even though I hate onions at least I can understand that they do at least provide flavoring so it makes sense to me why someone would use it in their burger. I do use onion powder in my seasoning mix.
But why lettuce and tomatoes? They're even the most common ones. (Obviously cheese too but that adds significant flavor too.)
@TenaciousGoat I guess those things are flavorless fillers there too. I usually get more meat in tacos when I request no lettuce or tomatoes. A chicken wrap is the same for me. I just remove the lettuce and let the sauce actually get onto the chicken.
