Preheat oven to 400 degrees Fahrenheit
For cauliflower, remove florets, wash and pat dry. The smaller the florets, the crispier they will be. Make sure they are not too big. Coat with 2 tablespoons of olive oil and season with Za'atar. Roast for 25 minutes, tossing half way through.
While cauliflower is roasting, chop kale and dice cucumber.
Once cauliflower is cooked, combine with kale, cucumber, feta and juice of one lemon. Add additional salt and pepper if desired.
Spread each wrap with 2 tablespoons of hummus. Divide cauliflower mix evenly amongst each wrap. Wrap and serve.
