What foods did the explorers introduce to America?

Explorers ate a lot of meat that was preserved in a lot of salt. Then also were known to eat bread, and for a celebratory treat, they would top it with Apple butter which did not easily go bad. Finally, they ate a lot of potatoes. Until they hit land, there was not a lot else that would stay on the long voyages over seas. Once they landed somewhere, they would be able to eat some of the foods (for example, fruits and vegetables) that were indigenous to the area.
