1.5 cups chocolate chips, I used Nestle chocolate, the one for kids’ drinks.
Chop or pound walnuts into smallish chunks.
In heavy saucepan, over low heat, melt chocolate chips with sweetened condensed milk and salt.
Remove from heat; stir in nuts and vanilla.
Line pans with waxed paper.
Spread evenly into wax-paper-lined pans.
Place in fridge for two hours or until firm. Cut in slabs or squares.
