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.)
The Calcium from the cheese might interfere with the iron from the meat or vice versa
better to have iron and calcium in seperate meals supposedly
but that is not a realistic easy nutritional goal to achieve
@N_Y_SparkyOxCable
I think a reasonable question is,vis the lettuce addedvto make the meat taste better or is the meat added to make the lettuce taste better
lettuce has almost no nutrition unless eaten in massive quantities but people think they are eating healthy if they add a little lettuce
Also think great depression, add some lettuce and they think they are getting more food even though lettuce is cheaper than meat
