What is jarred tuna?

Jarred tuna refers to tuna fillets that have been cooked, packed, and sealed in glass or plastic jars. The tuna is usually submerged in a liquid such as water, oil, or a flavorful marinade, and it can be used as a convenient ingredient for salads, sandwiches, and other dishes. Jarred tuna offers an easy way to incorporate protein and omega-3 fatty acids into meals without the need for refrigeration. It can be purchased from grocery stores and supermarkets and provides a shelf-stable option for quick and hassle-free meal preparation.
