HEAT oven to 400 degrees F. Spray a 15 x 10-inch jelly-roll pan with no-stick cooking spray.
COMBINE flour and salt in medium bowl. Cut in shortening using pastry blender or 2 knives until all flour is blended in to form pea-size chunks. Sprinkle with water, 1 tablespoon at a time. Toss lightly with fork until dough forms ball.
ROLL out dough between sheets of waxed paper to fit jelly-roll pan. Place dough in prepared pan, folding edges under. Flute edges. Prick crust with fork.
SPRINKLE cheese, ham, onions, parsley and pimentos evenly over crust. Beat eggs, cream, half-and-half, salt and pepper in medium bowl. Pour over filled crust.
BAKE 35 minutes or until set. Cool 5 to 10 minutes. Cut into 2 x 1 1/2-inch pieces.
Crust may bubble during baking and need to be pricked with fork again.
