How to make the Munich Mule via Common Man Cocktails

I need to get my hands on some Ginger Beer. I know this probably has a really great herbal looking taste. If you like more cocktail that use cucumber slices or vegetables, check out Tequila Salsa, Game of Thrones, and Burning Mandarin.

Recipe
1 1/2 oz Vodka
Diced Cucumbers
Fill with Ginger Beer
