Grease an 8 x 8 in or 20 x 20cm pan or line it with baking parchment across the bottom and up at least two opposing sides, so that the fudge can be lifted out of the pan by those ends.

In a large microwaveable mixing bowl, whisk together the sugar, cocoa and salt in mixing bowl.

Add milk and butter. Do not mix.

Cook uncovered in a microwave oven on high for 2 minutes.

Remove bowl from microwave and stir well to mix the ingredients together. Isn't it amazing how cocoa can turn that sugar and butter into rich chocolate?

Add the vanilla, pecans and mini M&Ms. Stir until blended.

Pour or spoon the fudge into your prepare pan.

Sprinkle on the extra nuts and/or M&Ms and press on them lightly so they stick.

Place in freezer for 20 minutes to cool and set.

Cut into small squares and serve.
