Seitan Shawarma

1 lb seitan, cut into squares
1 onion, sliced
1/2 tbsp turmeric
1/2 tsp coriander
1/2 tsp cumin
black pepper, cayenne, salt
4 tbsp olive oil
4 pita bread
pickles, sliced

Israeli (Palestinian?) salad:
cucumbers
tomatoes
parsley
green onions
olive oil
lemon juice

Tahini sauce:
1/2 cup tahini
1/4 cup lemon juice
1/4 cup hot water

Make the salad and tahini sauce ahead of time and chill.

Mix the spices. Combine the seitan and onion slices in a large bowl and sprinkle the spice mixture over them. Add 3 tbs of the olive oil and mix it all together. Grill the seitan and onions in a little bit of oil until browned. Grill the pita bread to give it grill marks and pile everything on top of it.
