With the entire ingredient mixed detailed above ready to go, get a big bowl to pour all the items into except for the romaine, Parmesan cheese, and croutons. The IKEA stainless steel kitchen mixing bowls are some of the easiest and best to work with, but any large bowl will do.
The key factor is that you can easily lift it later on, even with the ingredients all put inside. With the dressing ingredients added, use a hand whisk to blend and mix them evenly into a nice consistency.
Many think the lettuce should be thrown in the bowl as well. This is a mistake as it increases the time the lettuce parts soak in the dressing. Instead, the romaine pieces should be placed on a salad serving plate bare. The dressing then gets poured onto the lettuce for the presentation effect.
The croutons are then added last to stay as dry as possible until eaten.
