My 14 year old daughter is a picky eater, looking for advice

My daughter is very athletic, but does not eat healthy foods. She doesn’t eat meat other than chicken nuggets. She jokes about becoming a vegetarian. The only problem is she doesn’t eat ANY fruits or vegetables. Her diet consists of some dairy, but mostly processed foods and a lot of snack food and sweets. She eats mainly the same few things for each meal. The list of things she eats has only gotten smaller as she has aged. A lot of things seem to be a texture or smell issue. We have the few foods she eats on hand, but she is often with friends and will not eat or eat junk food when out. We met with a nutritionist a few years back that suggested we just continue to offer her things to try and not to force her to eat things she doesn’t want. This hasn’t helped. I don’t know if there is a professional to seek out with a specialty. I am open to any suggestions…
