2 egg whites
Pinch of salt
1/2 tsp. cream of tartar
3/4 c. sugar
1 pkg. mini chocolate chips
1 tsp. peppermint oil
Few drops green food coloring

Beat egg whites, salt and cream of tartar until stiff. Use a portable mixer. Beat in sugar and food coloring. Stir in chips. Drop by teaspoonfuls on cookie sheet covered with wax paper. Preheat oven to 375 F. Put cookies in oven then turn oven off and leave in overnight. Do not open door until morning!

Doubled recipe yields 6 dozen cookies; this will fill both oven racks.

These are also good using cherry flavoring and red coloring, instead of the peppermint and green coloring.
