Heat oven to 425°F. Line 2 cookie sheets with cooking parchment paper. In 2-quart saucepan, heat water, butter and salt to rolling boil over medium heat. When butter is melted, remove from heat; stir in flour all at once until blended.
Return to medium heat; cook 1 to 1 1/2 minutes, stirring constantly, until dough forms a ball and leaves a slight film on side of pan.
Remove from heat; stir in eggs, one at a time, stirring until thoroughly mixed. Stir in Parmesan cheese, chives and basil. On cookie sheets, drop by heaping teaspoonfuls 2 inches apart into 1 1/4-inch mounds, making 30 mounds.
Bake about 20 minutes or until golden brown and set. Remove from oven; with tip of sharp knife, make small slit in side of each puff to allow steam to escape. Bake 5 to 8 minutes longer or until dry and firm.
