How to use romaine lettuce at home
As with all produce, fresh is best. Try to eat romaine within a few days of purchase. You can buy hearts of romaine lettuce instead of the entire head. However, the outermost leaves are highest in nutrient density. No matter which type you buy, make sure to wash thoroughly to remove dirt and debris.
Romaine lettuce is probably best known for its use in Caesar salad, but is also delicious halved, brushed with olive oil, and grilled.
