Thanks for the suggestions. I think that I will definately add the lime juice and possibly cilantro. Just thought I would use the zest too. But maybe that would be too much. I will toss the avacoado in lime juice and add them too!
The recipe is from an internet site, just not sure which one. I printed it out a work some time ago, and the site is cut off the bottom of the page. I, as I am sure many of you do also, will see a recipe that "looks interesting" and print if off for later use!
But here is the original recipe:
Layered Southwest Pasta Salad
How much lime juice do you think? It will mixed with the oil, salt and cumin.
