1. Combine mint chocolate chips with shortening in a large microwave safe glass or ceramic bowl. Heat on 50 percent power for 2 minutes, stir (with a plastic or wooden spoon), then heat for an additional minute. Stir once again, and if chocolate is not a smooth consistency, continue to zap in microwave in 30 second intervals until smooth.
2. Use a fork to dip each wafer in the chocolate, tap the fork on the edge of the bowl so that the excess chocolate runs off, and then place the cookies side-by-side on a wax paper lined baking sheet. Refrigerate until firm.
Makes 108 cookies.
