Step 1

Buy good sardines. I get these at Costco. They are skinless and boneless.

Step 3

Toast your bread.

Step 4

Slice your onions very thin. Sprinkle with kosher salt. Really work the salt into the onions with your fingers. You want to bruise the onion slices a little bit so the salt will be absorbed. Add the vinegar and give it a couple more stirs.

Step 5

Mash the sardines with a fork. I just roughly mash them - I still want to have a few big chunks.

Step 6

Add a thin layer of sardines to your toast. Top with onion and tomatoes. Garnish with parsley.

Step 7

Enjoy!!
