Why yes!  As the parent you are still in control of what foods they’re given to eat.  So for starters serve them what you would eat and don’t just serve them what you think they’ll eat (stop the mac & cheese and chicken nuggets).  Introduce veggies in a fun way (like our green bean dance and making up funny names) and don’t make them think of them as a punishment.  Make pastas and soups with lots of vegetables in them.  Serve different vegetables at each main meal and as snacks— and see if they like some cooked over raw or vice versa.  Getting them involved in shopping, growing or cooking also helps.
