In case you've missed the radio commercials, the billboards, the cover story on yesterday's Showcase magazine in the Erie Times-News -- this weekend is the Key West Phest at Liberty Park.

I've never been because (I believe) it was always the weekend of Discover Presque Isle, but our family calendar is clear this Saturday and I'm thinking of taking the kids down to check it out. Margaritas, loud flowered shirts, sun, shimmering water, fun music and people everywhere celebrating the good life -- what's not to love?

Well, hate to spoil the fun, but those yummy frozen margaritas pack anywhere from 250 to 500 calories. If you're consuming 2,000 a day (less, actually, for most women) -- one margarita can be 1/4 of your days caloric allotment.

I know ... I know... girls (and guys) just want to have fun. Well, just so happens in my "inbox" yesterday I found this cool recipe from the ladies at HungryGirl.com for a 100-calorie margarita. So, in honor of this weekend's parrothead party, why not whip up a batch and save yourself 400 calories?

HG's Magical 100-Calorie Margarita
Ingredients:
6 oz. Sierra Mist Free (or Sprite Zero, or your other fave no-cal lemon-lime soda)
*1 shot of tequila (1.5 oz.)
1 packet **Crystal Light on the Go Lemonade (you may use 1/2 of the packet if you don't want your drink as intensely sweet)
2 tbsp. lime juice from concentrate (or fresh-squeezed lime juice)

Directions:
Mix all ingredients together. Pour over 1 cup of crushed ice. Enjoy.

*You can also make your margarita alcohol-free. This recipe, without tequila, contains just 10 calories (5 calories if you use only half of the Crystal Light packet).

**1 tsp. Crystal Light Lemonade drink mix may be substituted.
