What are some good finger foods for a baby without teeth?

Al
My little one is almost 10 months old and still no teeth. We don't do too well with baby food or cereal because she always fights me for the spoon but I still try to give her those once a day but it's a mess and most of it doesn't get in her mouth. She does great with things that she can feed herself. I give her little pieces of bread, chunks of cooked apple, chunks of banana, teething biscuits, and avacado slices. I want to try other things but I need ideas. What is your baby's favorite finger foods?
