You can use any of the following: Iceberg lettuce, Romaine lettuce or Butter lettuce. I prefer Butter lettuce because it is softer and doesn’t fall apart as easily as the iceberg lettuce does. Romaine works better than iceberg too. Broccoli slaw is found in a bag in the produce section of the grocery store, usually near the shredded cabbage or coleslaw. I love it because it’s yummy and there is no chopping involved.
