Use technology! iTunes app is a great motivator

The My Family Food app on iTunes engages the entire family in a healthy eating “competition” to complete individualized goals and earn “medals”. Each persons goal can be as small as a "touch", “bite” or as large a full sized age-appropriate serving; 1 time per day or up to 8 times per day per food group. It makes fun burp, cheer and bite sounds that my kids love.
