Once a year we go on a group camping trip and all combined there are about 30 of us. This year we are doing 2 group pot lucks where each family provides one themed food item, one themed drink and one theme decoration. Our themes are; a Mexican Fiesta and a Greek night.

On my hunt for the perfect themed drink I came across this recipe for Pineapple Margaritas on a blog I follow, rantingchef.com
Ingredients
2 cups lime juice, about 20 limes
2 cups white tequila
2 cups Triple Sec
2 1/2 cups fresh pineapple juice
Fresh pineapple slices, for garnish

Directions
Combine the lime juice, tequila, Triple Sec, and pineapple juice. Fill a cocktail shaker 1/2-way with ice and fill 2/3 full with the margarita mixture. Shake for 30 seconds and pour into glasses. Decorate with fresh pineapple slices and serve ice cold.
