Preheat oven to 450 degrees F. In a large bowl, toss bread cubes with 3 tablespoons olive oil, salt and pepper. Spread in an even layer on baking sheet and bake until toasted and golden – about 15 minutes. Remove from oven and cool slightly. Return bread to the large bowl. Add salami, cheese, tomatoes, onion, basil and cilantro. In a small bowl, whisk together remaining olive oil and vinegar. Drizzle dressing over bread mixture. Toss gently and serve immediately.
