Saute chik'n strips, tomatoes, leeks & celery together in olive oil. Mix in salt, pepper, and any other herbs you'd like to add. Heat through. Let cool.

To the cooled chicken mixture, stir in Veganaise (or similar) to your liking.

Stuff chicken salad inside a whole wheat pita with a leafy green of your choice (i put spinach on the ingredient list, but you could do collard greens/kale/arugula etc.)

Recipe travels well and is pareve!
