Suggestions on "creamy foods" for a child with texture issues?

My cousins are living with us, and the 2 yr. old has an issue with the textures of different foods. The things he'll happily eat without an adult coaxing him are pretty few. He is eating meats now, but when he moved in he would only eat hotdogs or bologna. My sister suggested hummus and avacado, so I'm needing more ideas if anyone has any. He doesn't have issues with breakfast or lunch foods, just dinner. Mainly veggies and meats. Any suggestions from people who have lived this would be great. He's improving, but I want the best variety for him I can get. Today I found out he'll eat salmon on toast with cream cheese, so encouraged by his progress!
