1 can crescent rolls (they now make it without seems)
1/2 cup chopped pecans
1/2 cup sugar
1/2 cup corn syrup
2 Tbsp butter or margarine, melted
1 tsp vanilla
1 egg, beaten
Heat oven to 350°F.
Unroll dough and press in bottom and 1/2 inch up sides of a 9x13-inch pan. Firmly press perforations to seal. Bake 8 minutes.
Meanwhile, in medium bowl, mix remaining ingredients. Pour filling over partially baked crust. Bake 18 to 22 minutes longer or until golden brown (mine took exactly 20 minutes).
Cool completely, about 1 hour, and cut into bars.
