Microwave Chocolate Fudge

2 Cups Marshmallows (either mini or regular or 1 jar marshmallow cream)
14 Ounces Condensed Milk
18 Ounces Semi-Sweet Chocolate Chips
1 1/2 Teaspoon Vanilla Essence
1 Pinch Salt

In a microwavable bowl mix marshmallows, milk and salt.  Cook in the microwave on high for 3-4 minutes or until the mixture has melted.  This will bubble to the top of the bowl...do not let it bubble over or you will have a big mess on your hands.  Stir the mixture together until it is smooth.  Add the chocolate chips and the vanilla until the chocolate chips have melted.  Spread fudge in a pan of your choosing (a square pan about 8in is good).  Refridgerate until firm (about 2 hours).  When firm cut and eat.
