In a large bowl, combine lettuce, cucumbers, and tomatoes.
In a small bowl, whisk together olive oil, lemon juice, garlic, sumac, salt, and pepper.
Drizzle the dressing over the salad and toss to coat.
Add toasted pita pieces and toss again.
Garnish with fresh herbs and serve immediately.
Notes
• Dress the salad just before serving to keep it fresh.
• Use fresh vegetables for the best taste and texture.
• Toast the pita bread until it's golden for extra crunch.
• Adjust the amount of sumac to your taste.
• Add herbs like mint or parsley for extra flavor.
