Prepare greens for salad. Combine egg, lemon juice, cheese, salt and pepper. Set aside. Combine oil and garlic. Saute croutons in 1/4 oil mixture. Combine remaining oil mixture with lemon mixture. Chill. After dressing is sufficiently chilled, place 3/4 of it in salad bowl. Add greens and 2 cups croutons. Toss. More dressing may be added if needed. Garnish with anchovies, if desired, and remaining croutons.
