Tried this last night with a guest list of 20 people. They loved it many said it was especially good because it was "different and delightful." We took the advice of a couple other reviewers... we added garlic, sweet chili sauce, toasted the walnuts and added a bit more tomato and parsley.
Option: Increase Parsley to 1/2 cup. Add - 1/2 tsp minced garlic, chili & garlic paste.
Try a dash of dark rum, just a little.
