Inspiration for this came from my local grocery store's deli counter. I love the flavor of the middle eastern spice za'atar with cauliflower but you can easily adjust this to your main course - Indian spices, Italian, even Asian spices - sesame oil, togorashi, etc would be yummy.
1whole head of cauliflowerwashed and base removed but leave the head in tact
1tablespoonza'ataror more or less to your liking
Salt and Pepper to taste
Preheat the oven to 375 convect roast or 400 regular roast or bake. Place the cauliflower on a baking sheet - I used parchment to line it for easy clean up. Rub the olive oil all over, then sprinkle on the za'atar and salt and pepper. Roast for about 1 hour checking at about 45 minutes for tenderness and to see if you need to cover it loosely with foil so the outside doesn't burn.
To serve, let it cool down a bit, then quarter it and enjoy.
