1 Sugar free Strawberry Crush singles to go drink pack (These are sold in grocery stores and at Walmart for a dollar a box. I have included a link in case you can't find it local.)
3 oz white tequila
1.5 oz lime juice
1 cup Ice
1/2 cup Water
Garnish: Lime slice and a strawberry
Combine all ingredients except garnish in a high powered blender and blend until smooth. Pour into a margarita glass, garnish with a slice of lime & a strawberry sliced across the bottom, and serve.
*Note: For a family/kid friendly version blend without the tequila out.
I use this blender and it is amazing:
