I want to make some homemade snacks like the Gerber puffs as finger food for my daughter -- any recipe suggestions?

I steamed peas and mashed them before spreading them out in front of my son when he's on his high chair. It's a great idea because I get at least 20 minutes of "peace and quiet" and he's distracted enough for me to do my own this. Brocollis also make a great easy finger food. My son sucks all the juice from it before gnawing and it. It's definitely messier because he throws the remains down once he's done with it.
