Slice all vegetables and fruits into small enough pieces to fit in your juicer (I use this one). Juice them in batches until complete. Strain juice through a fine mesh strainer.
Place 4 oz green juice, 2 oz tequila, and ice in a cocktail shaker. Shake then strain into a glass. Add desired garnishes then serve. Repeat this step for each green juice margarita you wish to make.
