Make the dressing ahead of time.
Whisk together all the dressing ingredients except for the oil and cheese.
1/4 C White Vinegar, 1 Egg Yolk*, 1 tsp Lemon Juice, 1 tsp Sugar, 1/2 tsp Garlic Powder, 1/2 tsp Onion Powder, 1/2 tsp Italian Seasoning, 1/4 tsp Kosher Salt, 1/8 tsp Black Pepper
Whisking constantly, slowly drizzle in the oil to emulsify everything together.
1/2 C Soybean or Vegetable Oil
Mix in the Romano cheese and chill for at least 30 minutes. (You may have to mix it again after chilling.)
1/4 C Grated Romano Cheese
Test the dressing for salt before serving. If necessary, you can thin the dressing out with 1-2 Tbsp of water. Make the Salad.
In a large bowl, mix the lettuce, onion, olives, tomatoes and peppers.
4-5 C Chopped Iceberg Lettuce, 1 C Chopped Romaine Lettuce, 1/2 Small Red Onion, Sliced Very Thin, 1 Medium Roma Tomato, Cut Into Wedges, 6-8 Whole Black Olives, 4-6 Whole Pepperoncini Peppers
Right before serving, toss the salad with the croutons and as much of the dressing as you desire. Serve topped with grated parmesan and maybe some fresh cracked pepper.
1 C Seasoned Croutons, Freshly Grated Parmesan, Fresh Cracked Black Pepper
