First "real" solid food

I've only ever given my baby purees. I have horrible anxiety of her chocking. It takes over and I get too scared to give her anything other than purees. She will be 9 months old next week and I know it's time to start giving her more food.

What did you start with? I want to start slow and with things that are the the least chocking hazard. I would love for some input.

I believe she is ready she tries grabbing at food all the time. I've given puffs she gags a lot. But I don't want to hold her back in terms of foods.

The anxiety is just so overwhelming sometimes.
