Put about 8 ounces of crushable ice cubes in a blender with blades that are capable of crushing ice. Add 8 oz of frozen (but thawed) strawberries in sugar sauce. (Available in the frozen foods section of your grocery store). Add sweet and sour mix and tequila. (Triple sec is not needed due to sweetness in strawberry sauce). Blend until desired consistency is obtained. Pour in large clear glass and garnish with a strawberry if available and a straw. The best Frozen Strawberry Margarita drink you've ever drank!
