Transition to Table Foods

Hello.

My baby has been eating baby foods for about 5 months. I started him on veggies, then added fruit. About 2 months ago, I started giving him veggie or fruit puffs (the kind that dissolve). My pediatrician has agreed that we can start trying to give him table foods but I'm unsure how to do that. I've read everything I can get my eyes on and I still can't figure this out. Please help!

For example:
- When they say carrots, should I mash them and feed him mashed food or should I slice them and feed him little sticks?
I have the same question for peas and green beans.
