Fiesta Ranch Pasta

I'm always looking for a new twist on Pasta salad for BBQs and misc.lucks.  I stumbled across this recipe, and it sounded like it was right up my alley.  It's a tasty treat, fun for a picnic on the 4th, and it feeds a crowd, as in, perhaps most of the armed forces.  Win!  Win!
The original recipe comes from butterwithaside.
