I finally found it! I've been making this recipe so long that I don't refer to a recipe anymore....and I could not for the life of me remember where it came from. Until today, that is.
Just for Julie...Yummy Quinoa Recipe (scroll down to the bottom of the post for the recipe description)
Changes that I make: I add a bunch of garlic to the onions and jalapenos and I always use mango salsa (it just tastes perfect this way, to me). Plus, I make much more at one time than her recipe calls for. And sharp cheddar cheese is a must too, IMO. :)
