ELI5: How can a cheeseburger from a fast food restaurant cost less than a peach from a grocery store?

The cheeseburger has meat, bread, cheese, pickles, ketchup, mustard and has to be made by a person. 

How can this be cheaper than a single piece of fruit (e.g: Peach, Pear, Orange, etc) sold at a grocery store?

Those fast food restaurants buy ingredients in such huge bulk that they pay very low prices. Also much of that food is highly processed and as a result it keeps for a long time. 

Much of the produce that grocery stores buy doesn't get purchased before it goes bad and has to be thrown out. And so the cost of all of that gets wrapped up into the price of the produce that people do actually buy.
