Shred Swiss and Gruyer cheeses.

In a microwave safe bowl, combine cheeses, cornstarch and wine.

Microwave in short bursts (1 min at a time), stirring in between, until all the cheese is melted and combined with the wine.

Stir in garlic powder and pepper to taste.

Transfer to fondue pot or a "dip" slow cooker and serve with bread cubes, crackers, pretzels or vegetables for dipping.
