Anybody know what these are?

I've been getting my cat Rachael Ray's cat food for about 2 weeks now. My cat has been extremely picky in how she likes eating (she does NOT like to eat wet food with ash in it), I have to be careful with her food budget so I haven't done a ton of blue buffalo/wilderness or anything like I'd like to. My question is if anyone knows what these square chunks are? I apologize as my cat just had her meal so it doesn't look great, but she avoids these bits a great deal. I'm trying to figure out what these are so I can either find some without these, or I can change her brand again to something that hopefully doesn't have these either. I've looked through the entire list of ingredients and it doesn't make sense what they are. Anybody?
