This is a loosey-goosey combination of recipes I've seen over the years. I usually just use what I have around but do try making up your own fun combinations.
Great for picnics served on a croissant, in a pita or on top of greens. Prepare the size of chicken and veg based on what you are using it for.... shred small and dice for sandwich or everything chunkier for a buffet or on top of greens for a nicer presentation.
Flavors intensify as it sits so it's really good the next day! Be careful how much onion you add if you are making a day ahead.
