If desired, you can substitute Grilled Chicken, Pan Seared Chicken, or Baked Chicken Breast.
Anchovy paste really does add that classic Caesar to the Caesar dressing, but Worcestershire sauce works too (or a Worcestershire substitute). If all you can find is whole anchovy fillets, blend 2 anchovy fillets to make 1 teaspoon anchovy paste. Keep in mind that anchovy paste has added vinegar and spices and is milder in flavor.
Add different proteins to this salad to make it work for different diets, like Canned Chickpeas, Baked Salmon, or Sauteed Shrimp. For vegan, use Vegan Caesar Dressing.
