Sunflower seeds are fine. Charlie has those in his dish. Other than that, try giving him veggies if you have some, nothing with a pit, like a peach or avacado... um... leafy green veggies are the best, and I have heard citrus can kill them... I dunno, but just to be on the safe side, maybe don't! Also try noodles... just plain noodles, Charlie loves cooked noodles. Good luck!
