Having a picky eater in the house is a real challenge sometimes. Sometimes they do not like what you have made for the rest of the family.
Sometimes they are being picky just for the sake of being picky. Either way, they can be a real pain. However, there is hope and you do have some options.
Picky eaters are not picky due to food allergies or some medical condition. Picky eaters will only eat certain foods, disregarding the rest.
Do not make them their own meal. You are normalizing their behavior by doing this. They need to get to know about other foods. They should eat what everyone else is eating.
Some kids are picky eaters because they are only eating those foods. They need to get to know other foods before they get too fussy. Sometimes learning about other foods will help to broaden their horizons, making them less picky.
