Preheat oven to 450°F-500°F/ 230°C -260°C.
Slightly cut the base of the cauliflower but make sure to keep the leaves.
Bring 2 gallons of water and one tablespoon of salt to a boil in a large pot over high (ensure the pot is large enough to fit the whole cauliflower).
Boil the cauliflower for 10-15 minutes until tender.
Take the cauliflower out of the water and let it cool down to room temperature.
Rub 1-2 tablespoons olive oil between hands, then rub over cauliflower to apply a thin, even layer.
Season with garlic powder, salt, and pepper to taste.
Bake in preheated oven until dark brown, about 20- 25 minute
Remove from oven, and carefully rub with one tablespoon of olive oil.
Season more if needed, serve hot (with or without Pita).
