Hamburger

Hamburger is an item that can only be obtained through Crafting. It is not found as a natural pickup or direct loot source, so players must first unlock or access the relevant recipe before they can make it.

Because its only documented acquisition method is crafting, Hamburger belongs to the group of player-made consumables rather than scavenged supplies. If you are looking for one, the practical requirement is to gather the needed ingredients and use a crafting station or menu that supports the recipe.
