If you are a sous chef, I believe that you have already got skills and asking this question suggests that you are not confident about your skills.
Well, If you were a fresher without any skill I would have suggested that you can't do it but since you are already a chef with 7-years of experience, you can enhance your skills by watching videos online and practicing those recipes at home. You can also purchase books and read them. See, culinary is an art that you will learn only by practice.
