lettuce hearts

Listings commonly offer lettuce hearts as whole hearts, chopped, or loose.

Options in listings include pre-washed/ready-to-eat or marketed as 'ready to use', while other entries list lettuce hearts as raw ingredients.

Packages are commonly sold as single packs or multi-count packs; examples in listings include package quantities of 1 and 3.

Common features include 'pre-washed' or 'ready-to-eat' labeling, resealable bags on some packages, and claims that the product contains no preservatives.

Listings advise refrigerating the product, following the use-by date on the label, reclosing and refrigerating after opening, and storing in the refrigerator crisper to help keep lettuce crisp.

Listings highlight that lettuce hearts are sources of vitamin A and vitamin K; some mention 'more iron than spinach' for a specific variety and another lists 'Only 15 calories per serving.'

Some entries list the United States or the United States and Mexico as country of origin, other listings state the country of origin varies, and at least one notes processing in the USA.

Customer reports vary: many reviewers note lettuce hearts are fresh and crisp at purchase and keep well in the fridge for several days; one reviewer reported it lasting about 1–2 weeks when not used frequently.
