Marinate: Slice the chicken breast if desired, and either place it in the marinade bowl and cover it with plastic wrap, or place it in a plastic bag and pour the marinade over top.

Notes
Chop up fresh cilantro for this recipe! Don't worry about stripping the leaves off the stems; the stems have the most flavor! Note: If you're using parsley instead, remove the stems, as they're bitter.
If you're using sliced chicken, you only need to marinate it for about 30 minutes to get decent flavor. But remember, the longer, the better!
You can use whatever citrus juice you prefer for this recipe; if you can find sour oranges, they're incredible!
Got spare marinade? Let it simmer in the pan after making fajitas for 5 minutes to ensure it's safe to eat, then use it to cook your peppers and onions.
