This dish always comes out delicious, even with changes to the ingredients. I have made it with salmon, halibut, red snapper, swordfish and tilapia. You can control the heat by the amount of hot pepper you use. If you don't have a jalapeno on hand, substitute 1/4 tsp cayenne pepper ( I usually use both in this recipe). If you don't have za'atar spice blend, use 1/4 tsp thyme, 1/4 tsp marjoram, 1/4 tsp oregano, 1/2 tsp roasted sesame seeds and 1 tsp sumac for this recipe. This looks as good as it tastes!
