In a small bowl or glass measuring cup, whisk together the olive oil, vinegar, Worcestershire, honey, lemon juice, garlic, oregano, salt and pepper until well combined. You could also use an immersion blender.
Meanwhile, prepare the ingredients. Place the chopped tomatoes, green peppers and drained chickpeas in three separate bowls. Pour about 1/4 of the prepared vinaigrette dressing over each so they can marinate. Reserve the rest of the dressing for the lettuce.
Sauté the cubed salami with a small splash of olive oil in a non-stick pan over medium heat until it is browned. Drain the salami on paper towels.
Put the chopped lettuce in a large bowl. Pour over the remaining vinaigrette and toss to coat.
Add the marinated green peppers, tomatoes, chickpeas, cooked salami and mozzarella pearls to the bowl and toss again. Serve immediately.
