1Heat oven to 425°F. In medium bowl, cut shortening into Bisquick mix, using pastry blender (or pulling 2 table knives through ingredients in opposite directions), until particles are size of small peas. Sprinkle with cold water, 1 tablespoon at a time, tossing with fork until all flour is moistened and pastry almost cleans side of bowl (1 to 2 teaspoons more water can be added if necessary).
2Gather pastry into a ball. In ungreased 9-inch quiche dish, press pastry evenly in bottom and up sides. Bake 12 to 14 minutes or until pastry just begins to brown and is set.
3Reduce oven temperature to 325°F. Sprinkle bacon, cheese and onion into crust. In medium bowl, beat eggs slightly; beat in remaining filling ingredients. Pour into crust.
4Bake 45 to 50 minutes or until knife inserted in center comes out clean. Cool 10 minutes before serving.
