This salad is best when it sits for 4 to 6 hours after being assembled so plan accordingly.
Wash and dry the romaine lettuce and cut into bite sized pieces.
In a large bowl, add the juice from the two lemons, finely slice the chives and add to lemon juice, add the mayonnaise, oil, Beau Monde seasoning, and whisk well. Start with a small amount of the seasoning and taste and add more until it is to your liking.
To the dressing, add the fresh mozzarella. I leave the balls whole, you can dice the cheese if you like. Cut the corn from the cob and add this to the dressing. If you are using the avocado, dice and add as well as the red onion if using. Give this all a good toss.
Top the bowl of dressing and other ingredients with the chopped romaine, but DO NOT mix it. Let it sit on top of the rest of the ingredients. Cover and refrigerate for 4 to 6 hours.
When ready to serve, remove from fridge, toss, and top with lots of black pepper.
