I have a 19 month old son. He eats just about anything under the stars. Right now is your golden opportunity. She isn't being really picky so try to expose her to a large variety of foods. I did that with my son and he has a great taste for vegetables, fruits, mexican, chinese, just about anything. I give him cooked (from frozen) broccoli, cauliflower, and carrots without any other seasoning on it. He loves canned carrots and sweet potatoes.
If you aren't giving your little one enough, believe me she will be the first to let you know. Between meals, I tend to set out things like raisins, fig cookies, chopped prunes, or bananas just to supplement and he does fine. I hope this helps to answer your questions a bit. Let me know if I can help any more. Good luck, Shannon G.
