Miss America Mallory Hagan -- Stomaching Life After the Pageant

It's only been one month since Mallory Hagan won the title of Miss America 2013 ... after KILLING IT in the swimsuit competition ... and it appears she's back to eating like a normal human being again.

24-year-old Hagan was spotted rocking a pink bikini in Hawaii yesterday ... still looking incredible ... with a little more to love.

Sometimes ya just gotta let loose.
