Add margarita mix and water to Ninja Creami Deluxe container. Freeze for 24 hours.
Wet the rim of a glass with lime juice or water and press into salt for a salted rim.
Remove Creami container from freezer and pour in tequila and then process on FROZEN DRINK setting.
Pour frozen margarita into glass. Squeeze a little lime juice on top and serve with a lime wheel or wedge.
Notes
If salting the rim of your margarita, make sure to do it before adding the margarita!
You can adjust the strength of your margarita by adding more or less tequila versus water when processing. For a less strong margarita, you can do ¾ cup tequila and ¼ cup water.
To make a mocktail version, simply add margarita mix and water and leave out the tequila. Add water when blending instead of tequila.
