Study shows that the most popular breakfast in America is . . . COLD PIZZA? I’ve always loved cold pizza for breakfast! Is that weird? What did you have for breakfast today . . . maybe some eggs & bacon, bowl of cereal, or maybe a bagel? Leftover pizza seems to taste better right out of the fridge to me. There’s a new survey that came out that reported the most popular breakfast food in America is . . . cold pizza. A whopping 53% of people say they’d rather have a cold piece of pizza for breakfast than any of the traditional breakfast foods. So don’t throw out that leftover pizza. Enjoy it for breakfast!
