In a large bowl, mix together the iceberg lettuce, cut tomatoes, celery stalks, Swiss cheese, ham, and Spanish olives.
Mix garlic, oregano, and Worcestershire sauce in a bowl. Beat until smooth with a wire whisk. Add olive oil, gradually beating to form an emulsion. Stir in vinegar and lemon juice and season with salt and pepper. Add dressing to salad and toss well. Add Romano and toss again.
