I slice the romaine into thin ribbons. Washing in ice-cold water keeps it crisp. Using a salad spinner, I dry the leaves thoroughly to prevent a soggy salad.
I mix olive oil, lemon juice, salt, pepper, and optional oregano in a small bowl or mason jar. Shaking the jar makes combining easy, and I can store leftovers right in it.
In a large bowl, I combine romaine, dill, scallions, and feta. At this stage, you can prep ahead and refrigerate before dressing.
I drizzle the dressing over the salad and toss gently with tongs, massaging the leaves slightly. This lets the flavors blend, and the feta adds a creamy touch.
