Preheat the oven to 400 degrees. Line a baking sheet with nonstick aluminum foil.
Spread the cauliflower on the baking sheet. Add the garlic and anchovy fillets. Drizzle with olive oil and sprinkle with salt and pepper. Roast, stirring once, for 15-20 minutes, until the cauliflower is golden brown and tender.
Transfer the cauliflower mixture to a food processor and process until smooth. Stir in the lemon juice. Transfer to a serving bowl and serve hot with pita wedges.
