Prepare all of the ingredients as indicated above, so that they are ready to add to the salad. Wash and chop the veggies, thaw the peas, and cook the eggs and bacon.
To make the dressing, in a bowl combine the mayonnaise with parmesan cheese, pepper, and sugar.
Assemble the salad in layers in this order: lettuce, red onion, cherry tomatoes, peas, eggs, dressing, cheddar, bacon, and green onions if using.
When adding the eggs, arrange the sliced eggs around the outside of the bowl so that the yolks are visible, then fill in the center with the chopped eggs.
When adding the dressing, be sure that the layer extends all the way to the edges of the bowl to seal in the other ingredients.
