My kids are fussy eaters too. When they were smaller, what really helped was to let them assist (when safe) with food preparation. Also when they were bigger, I would tell them what each nutrient did for their bodies and how they helped (e.g. iron makes you strong and gives you super powers!). Another tip is to 'hide' nutrients in your child's food. So, add chopped spinach (for iron) to her rice, or mix it through a savoury pancake batter (or in whatever she does like to eat). Hope this helps!
