J.S.
I went with anything I could cook to be soft then cut up. Potatoes, sweet potatoes, carrots, broccoli, cauliflower, etc. Also, diced soft fruits like bananas, kiwi, peaches, pears, etc. Cut toast into strips that he can hold onto and chew on. My girls really liked that. Scrambled eggs were also a hit at my house at this age, but I'm told they can be an allergy problem for some, so try a small amount first and wait for any reaction before giving too much of these.
I avoid canned foods as the cans are lined with a thin plastic coating (to minimize metalic taste) that can leach plasticizers into the food. Best to go fresh if possible, or frozen if not.
Have fun and be prepared with a wash cloth! :o)
