Bezos joked with reporters that he did not have his "last meal" before taking off on his space travel company's first flight with people on board.
As the Amazon and Blue Origin founder served food to members of the press gathered at the remote rocket launch site in the West Texas desert, one reporter jokingly asked: "Is this your last meal?"
"Hey, did somebody say 'last meal?'" Bezos, wearing a cowboy hat and sunglasses, responded to laughter. "I don't think we should put it that way. Let's talk about it in a different way."
Chicken thighs, mac 'n' cheese and black-eyed peas were on the menu -- a "favorite" recipe by Bezos' grandmother. He also handed out copies of the recipe.
"Now, if you don't like this, just keep it to yourself," Bezos said to more laughter.
Bezos told reporters that he and his three crewmates had finished their training.
"We're going to have a little refresher early tomorrow morning," he added. "We have an early wake up tomorrow."
