Getting a mite picky

Draya used to take and eat pretty much any food I gave her. Now, my usually not so selective child has a new habit of taking food in her mouth, storing it for a while and then spitting it ALL back out again. Things she used to like, hamburger and shredded cheese for example, are no longer yummy. Yesterday I specifically ordered a second patty on my burger to feed her and 95% of it ended up in me because she just wasn't interested. Feeding time is getting to be quite interesting! Meats and protein are touch and go. In fairness she's never really like the baby food brands. Thankfully cottage cheese and mini-go are still huge hits, for now. I'm going to pick up some all beef hotdogs and see if she'll eat them. Any other suggestions?

Update: The hotdogs were a bust. She didn't like them at all
