How to make sushi without the raw fish?

I really like the taste of sushi (vegetarian preferably) does anyone have a good recipe to making sushi without fish, imitation crab, or shrimp? Can it be made with chicken instead (cooked of course) ? Or a good sushi recipe for vegetarian would be nice as well. thanks!

Cream Cheese and Crab Sushi Rolls

Ingredients-
1 cup uncooked white rice
2 cups water
2 tablespoons rice vinegar
1 teaspoon salt
2 sheets nori seaweed sheets
1/4 cucumber, peeled and sliced lengthwise
2 pieces imitation crab legs
1/2 (3 ounce) package cream cheese, sliced
1 teaspoon minced fresh ginger root

Directions-
Bring the rice and water to a boil in a saucepan over high heat. Reduce heat to medium-low, cover, and simmer until the rice is tender, and the liquid has been absorbed, 20 to 25 minutes. Stir in rice vinegar and salt. Allow to cool completely.
Lay out seaweed sheets. Moisten hands with water, then spread the rice evenly on each sheet, leaving a 1/2 inch gap along one edge, lengthwise. Arrange strips of cucumber, imitation crabmeat, and cream cheese in a straight line along the side opposite of the gap. Roll the sushi from the toppings to the exposed end of the the seaweed sheet.
Using a sharp wet knife, slice each roll into 5 or 6 pieces. Serve with minced ginger on the side.
