I agree with the posts about skipping the jarred baby food, but you could always ask why. I fed my kids table food at that age (an a little younger, although I made baby food for both kids)--either soft things or things that are easily gummed, mostly cut very small. Well cooked diced vegetables (so they're soft), egg yolks (scrambled or hard boiled--you can add the whites at 12 months), tofu (I flavored it with a little soy sauce), diced soft fruit, crackers, cherrios, those little melt in the mouth baby snacks they make, diced avocados or sliced olives (both high in health fats), etc.
Now if your son does well those foods and has teeth, he might be getting ready for more complex food and you can gradually introduce the foods the rest of the family are eating. You just want to watch out for choking hazards (of course) such as grapes, popcorn, hot dogs, honey, peanut butter, etc. Good luck.
