Brisling Sardines boast a delicate flavor and firm texture. All varieties are lightly oak-smoked and hand packed in either pure olive oil, spring water, or tangy mustard. Just one can provide about one-third of the protein needed every day. Brisling Sardines are an excellent source of calcium and contain about 2 grams of omega-3 per serving. Try them in salads, sandwiches, or casseroles.
