We've just hit the picky stage as well and its been a bit of a shock because Abe has been eating EVERYTHING and now its hard to get him to eat at all. And Savannah didn't get to this point until she was almost 2 so I wasn't expecting it. But we're pretty much into breads/pasta(usually)/bananas, but a like you said--a lot less of it, quesadillas and avocados. Protein has gotten hard--sometimes beans work, either in little mini burritos or whole beans, but not really often. And all the meat, chicken, fish he used to eat is thrown off the table instantly. And he won't drink milk either, but he usually eats cheese and yogurt.
Sounds like she's getting dairy, and some fruit--if you can sneak veges in somehow (is a smoothie or pasta sauce or something), then that would be good. But she really is hitting the food groups.
I also try to keep offering just a tiny bit of something new (or something they used to like) just to keep them in the habit of seeing it and you never know when they will decide to eat it. Savannah still surprises me some days and picks up a food that she hasn't touched in months and eats a good sized serving. Doesn't happen often and I get kind of annoyed by how much they won't eat, but supposedly they do come around in the long run.
