First, wash the cauliflower florets under cool running water and pat them very dry with a towel. Removing moisture is key so the batter sticks and fries up crisp. I always double‑check they’re dry before moving on.
In a bowl, whisk together the flour, cornmeal, smoked paprika, and garlic powder. Slowly pour in cold sparkling water while stirring until you get a smooth, slightly thick batter. The bubbles make the coating light and crisp.
Heat a shallow layer of high‑smoke‑point oil in a skillet until shimmering. Dip each floret into the batter, let excess drip off, and fry them until deeply golden on both sides. Once crisp, transfer to paper towels to drain briefly.
While cauliflower fries, whisk Greek yogurt with tahini, lemon juice, minced garlic, and sea salt. Add chopped parsley for freshness and adjust with water if it’s too thick. This creamy sauce brings the whole sandwich together.
Gently warm the pita so it’s pliable, then spread a generous spoonful of sauce inside. Layer shredded lettuce, diced tomatoes, and pickles, and fill with the hot crispy cauliflower. I like to drizzle a bit more sauce on top before folding.
