I love sardines right of the can.
That's how I eat them all the day. A perfect lunch to pack to work. All you need is a toothpick (or a plastic fork for the mushier ones) to eat them with.
I prefer the sardines with skin and bones and packed with olive oil. This is the most nutritious version.
King Oscar Mediterranean Style is my favorite brand.
On a cracker with hot sauce on top.
I don’t buy them much because I’ve never seen anything but Product of China.
