Ever wonder what to do with that bag of veggies you have leftover after finishing your take-out order of Vietnamese soup (pho)? Usually just trash the bag of bean sprouts, basil and limes? Well here is something useful for them - my friend called it "Viet Guac" as a joke, but I ended up making it. And wouldn't you know it? It actually turned out to be pretty tasty, especially with the caramelized onions I still had in the fridge. I served it with Tostitos' hint of lime flavored chips, or the plain is fine, too. Time doesn't include how long it takes to make caramelized onions - if you're in a hurry, raw or slightly sauteed is fine, too. Just add a little sugar to taste. I add brown sugar to my caramelized onions, so it made it nice and sweet, for kids' tastes.
