Avocado makes a brilliant swap for the egg and oil in this creamy Ceasar dressing. The lemon keeps the avocado from browning and the swap tastes fantastic, making this salad a healthy choice.
To make the dressing, blend all of the ingredients except for the cheese, romaine, and tomatoes, in the blender until creamy and smooth. Chill.
Toss the salad greens with the dressing, garnish with the cheese and optional tomatoes. If you have leftover dressing, it will keep without turning brown, for a few days in the refrigerator.
