Quickly or just to get you started:

Vegetables, fruit, or insects are great for discussing likes and dislikes. Fruit - likes, insects -dislikes, vegetables a mixture.

Emotions bring up a lot of conversation. What makes you ~? What do you do when you are ~? or simple 'Are you hungry?

Places around town also come with a large amount of discussion. Who works there? What are they called? Have you ever been there? Do you go there a lot? Where do your parents work? ...

Jobs are along the same line. What does he do? Where does she work? What do you want to be in the future? Where do you want to work? ...

Nature. What kinds of things can you find around where they are? Have they ever been to the ocean? an island? the jungle? What lives in a pond? in a cave? in a hole? ...

Animals!
