2 c. semi-sweet chocolate chips
1 c. milk chocolate chips
2 c. miniature marshmallows
1 14 oz. can sweetened condensed milk
dash of salt
1 tsp. vanilla
1 c. chopped walnuts

Microwave in a one quart glass container. Cook on high for 2 1/2 to 3 minutes until all is melted. Stir after each minute. Stir in vanilla and nuts. Spread into a buttered 1 1/2 quart dish. Takes quite a while to harden enough to cut smoothly. This never sugars.
