This goes over well at potlucks - when there's a choice of more than one pasta salad, this one usually goes first. Oddly enough, the leftovers make good soup, too! I just add the leftovers to some vegetable broth and canned tomatoes, and season it with more of the same spices that were in the recipe. This recipe originally came from allrecipes.com, but I have tweaked it in a way that suits me better. As always I have cut back on the oil and lime juice, so add more back in if it suits you. I love the amount of chili powder and cumin in this, but it may be a bit much for some so use less if you don't like those flavors as much as I do.
