How Many Calories Is 1 Slice Of American Cheese I Trying To Figure Out How Many Calories I Consummed At Lunch.?

I trying to figure out how many calories I consummed at lunch.? - how many calories is 1 slice of american cheese

I went into the underground site, but not really helped. I had a tuna wrap with 1 slice of American cheese, pickles and a little light mayonnaise. I know I can create an exact, because we do not know, enter the portion size, but an estimate would help.
Thanks
