Kids will be happy to eat these veggies parading as sushi. Flatten 2 slices of bread with a rolling pin. Mix together 3 tablespoons cream cheese and 1 1/2 tablespoons sour cream; spread over slices. Lay two carrot and two cucumber matchsticks (6 inches long) at the bottom of each slice -- let hang over edges. Roll up bread, pressing gently to seal, then cut each roll in four equal pieces.
