@raynbow- If you haven't tried the different types of sardines, you may be surprised at how many varieties are available. You can get them packed in different types of oils like soy or olive oil, and in various seasonings including mustard and hot sauce. Sardines also come smoked or steamed, or packed in water for people who prefer to add their own toppings and seasonings.
Some people don't like the skins, bones, and fins that most canned sardines have. Some brands of sardines come completely bare, which is very appealing to a lot of sardine connoisseurs. I suggest that you take advantage of the many sardine varieties available to make eating these small, nutritious fish more interesting.
