Heat oven to 350 degrees F.

Melt chocolate chips from zip-top bag in a saucepan over lowest heat. When chips begin to melt, remove from heat; stir. Return to heat for a few seconds at a time, stirring until smooth. Cool to room temperature.

In a mixing bowl, combine melted chocolate chips, 1/2 cup softened margarine, 2 teaspoons vanilla, and 2 whipped egg whites. Stir until smooth. Slowly add the remaining contents of the jar to the melted chocolate mixture. Mix just until moistened. Drop dough by rounded tablespoons onto prepared baking sheets. Bake for 12 minutes or until edges are set, but centers are still soft.
