WATERMELON MARGARITAS

I made these for our Father's Day BBQ.  They were delicious.  The recipe came from the July 2010 edition of Cooking Light.

INGREDIENTS
3.5C cubed seeded watermelon
.5C tequila
2 TBSP Sugar
3 TBSP fresh lime juice (about 2 limes)
1 TBSP Triple Sec

DIRECTIONS
Combine watermelon and next 4 ingredients (through Triple Sec) in a blender; process until smooth.  Garnish with lime wedge or melon ball.
