We really enjoyed this. I used all the ingredients listed, but I assembled it a bit differently since I was making this for my husband to take to work and didn't want the pita getting all soggy. I mixed up the tuna ingredients and packed that in one container. In a large bowl I tossed the spinach, tomato, red onion, feta (and I threw some diced cucumber in there too.) Then I sent along an Italian Herb tortilla wrap kind-of thing. He assembled it all at work and said it was delicious.
