What are some good vegetarian dishes to serve at my son's 2nd b-day party?

Take 2 bars of Philly cream cheese and microwave them for a minute. Mix them with 2 cups of sour cream. Then mix in four cups of shredded cheddar cheese. Then mix in a little green onion. Stir it all up. Then spread this mixture thinly onto extra-large flour tortillas and roll them into a tube (like a roll-up sandwich). Refrigerate the tubes for 3 hours and then slice them into 1-inch segments. Serve them with salsa. AWESOME flavor and meat-free. And what kids don't like cheese?
