Preheat the oven to 350 degrees F. Pour the chocolate chips into a small 9-inch skillet (cast iron is perfect).
Bake in oven for about 3 minutes, until chocolate is melted. Arrange the marshmallows on top (the 30 is an approximate, depending on the size of the skillet).
Return to the oven and bake an additional 2-3 minutes, until marshmallows are toasted.
Serve warm dip with graham crackers, pretzels, or fruit.

Notes
Want a peanut butter dip? Try peanut butter chips in place of the chocolate OR use half chocolate morsels and half peanut butter.
