If you are looking to add some extra spice, use a spicy salsa, or add a dash of cayenne or sriracha.
The lime juice is really optional, but if you're making this with the Turkey Taco Burgers then you have 1/2 a lime to use up!
Have some fresh herbs to use up? Chop up some cilantro or parsley for a fresh addition!
Best if made at least an hour before serving so that flavors can combine.
