Heat oven to 375. Combine flour and salt in medium bowl; cut in butter with pastry blender or fork until mixture resembles coarse crumbs. Stir in chives and water just until flour is moistened. (Mixture will be crumly.) Shape into ball; flatten slightly.
Roll out dough on lightly floured surface into 12 inch circle. Fold into quarters. Place dough into ungreased 10 inch quiche pan or 9 inch glass pie pan; unfold, pressing firmly against bottom and sides. Trim crust to 1/2 inch from edge of pan. Crimp or flute edge of crust.
Sprinkle cheese and bacon over bottom of crust. Place asparagus spears in spoke pattern on top of bacon.
Combine all remaining filling ingredients in small bowl. Pour over asparagus-cheese mixture. Bake for 40-45 minutes or until golden brown and set in center. Let stand 10 minutes before serving. Serve warm.
