This is one of those areas where you have to know someone, maybe. Try volunteering your cook experience at a lot of community events. Or get a part time job doing cooking for an event vendor. Then get a letter of recommendation from those events after you have worked them for a few times. Really, it seems that no one will take a chance on an applicant unless they come with personal recommendations or a letter about their performance at volunteer work. It really is about who you know and showing who knows you. That is just the way it is here. Good luck.
