Beat brown sugar and margarine at medium speed of a mixer until light and fluffy. Add molasses and egg white; beat well. Stir in crystallized ginger.
Lightly spoon flour into dry measuring cups; level with a knife. Combine flour, wheat germ, baking soda, ground ginger, and cinnamon. Stir into molasses mixture. Cover; freeze 20 minutes.
Preheat oven to 350°.
Lightly coat hands with cooking spray. Shape the dough into 30 balls, about 1 tablespoon each. Roll the balls in the granulated sugar. Place the balls 2 inches apart on baking sheets coated with cooking spray. Bake at 350° for 10 minutes. Cool cookies on pans for 3 minutes. Remove from pans, and cool the cookies completely on wire racks.
