Picky toddler, help please.

My daughter just turned a year an half on the 22 an when she was a baby she was a great eater ate anything you gave her and seemed to love it. Ever since we moved into our new house about 6 months ago she has become so picky on what she'll eat. She won't eat meat once an a while I can't get her to eat chicken nuggets. An fruit she will eat no problem, but vegetables have become a pain lately here too any ideas on how to get her to eat right again? Or meal plans I could try?
