Add the tequila, lime juice and simple syrup to a shaker with ice and shake.
Strain into a chilled glass or a rocks glass filled with fresh ice.
Garnish with a lime wheel.
Notes
Simple Syrup - Simply combine equal parts sugar and water over medium heat until the sugar dissolves. Cool and store in an airtight container in the fridge for up to 30 days.
Create a gin gimlet or vodka gimlet by subbing out the tequila.
