Preheat oven to 200°C. Combine the oil and garlic in a small bowl. Cut the Lebanese bread into wedges and use a small pastry brush to brush all over with the oil mixture.
Place the bread wedges on 2 baking trays and bake in a preheated oven for 7 minutes or until crisp and golden.
Meanwhile, to make the lentil and tomato salad, place the lentils in a sieve and rinse well under cold running water. Drain well and place in a large bowl. Add the tomatoes, parsley and onion to the lentils. Toss to combine.
To make the dressing, place the oil, lemon juice, garlic, lemon rind and cumin in a small bowl, and whisk to combine. Taste and season with salt and pepper.
Pour the dressing over the lentil salad and toss to combine. Serve with wedges of garlic bread.
