2 eggs white large
1 tablespoon white vinegar
1 teaspoon vanilla extract
1/4 teaspoon salt
2/3 cup sugar
1 cup pecans finely chopped
1 cup semi-sweet mini chocolate chips
Preheat oven to 275°. Grease baking sheets.
In a large mixer bowl at high speed, beat egg whites, vinegar, vanilla and salt until soft peaks form. Add sugar and beat until very stiff and glossy and sugar is almost dissolved. Fold in pecans and chips. Drop by well-rounded teaspoonfuls about 1 inch apart on baking sheets.
Bake for 20 to 25 minutes or until set and dry to the touch. Cool cookies on wire racks,
