The Hero and His Elf Bride Open a Pizza Parlor in Another World (light novel)

"After a pizza delivery bike slammed right into me, I was sent flying into another world where a goddess had three options as to how I might be reborn. Apparently, though, some other guys got there before me and snapped up the sword-wielding and magic-hurling options, leaving me to...save the world with pizza?!? I never asked to be a high calorie hero!!"--
