Halve your romaine lengthwise, lay on your cutting board cut-side down, and chop it into bite-sized pieces.
Place your chopped lettuce in a large salad bowl.
Add the chopped avocado then drizzle with the fresh lemon juice.
Add in the fresh lemon zest, shaved parmesan cheese, and olive oil.
Season with sea salt and pepper to your taste.
Toss to combine and serve!
Enjoy!
