Preheat the oven to 220C, fan-forced. Line an oven tray with baking paper. Coarsely chop the cauliflower stem, then cut the head into medium-sized florets. Thickly slice the capsicum. Crush or finely chop the garlic.
Step 2 — Roast vegetables
Combine the garlic, half the Spanish seasoning*, ½ tsp turmeric* and 1 tbs olive oil in a large bowl and season well with salt and pepper. Add the cauliflower and capsicum and toss until well coated. Put on the lined tray and roast for 20 mins or until golden and tender.
Step 3 — Prep salad ingredients
While the vegetables are roasting, trim half the lettuce*, then shred. Cut the cucumber lengthwise into thin wedges. Pick the mint leaves, discarding the stems.
Step 4 — Heat pita
When the vegetables have roasted for 10 mins, enclose 2 pita* in foil. Put in the oven for 8 mins or until heated through.
Step 5 — Prep lemon
Meanwhile, finely grate the zest of half the lemon, then juice the half. Cut the remaining lemon into wedges.
Step 6 — Get ready to serve
Combine the vegan mayonnaise, 1 tsp lemon zest* and 1 tsp lemon juice* in a bowl and season with salt and pepper. Spread the pita with the lemon mayonnaise, then fill with the roasted vegetables, lettuce, cucumber and mint. Serve with the lemon wedges.
