Boil the potatoes: Add potatoes to a large pot of cold water with 1 tablespoon of salt and ½ teaspoon baking soda. Bring to a boil over high heat and once boiling, reduce heat to keep at a simmer. Cook for 12-15 minutes or until potatoes are fork tender. Once the potatoes are cooked, strain them.
To a large bowl add the sardine and use a fork to mash it into smaller pieces (don’t fret about any fish bones, they are very tiny in sardines and A-OK to eat).
Then, add the olive oil, lemon juice, pressed garlic, kosher salt, ground pepper and mustard and stir to combine well with the mashed sardines.
*If your baby potatoes on the larger side, feel free to halve or quarter the cooked potatoes before adding to the bowl*Add the cooked potatoes to the mixture in the large bowl and toss a few times to coat (it's ok if the potatoes are still warm!)
Add the finely chopped red onions, halved baby tomatoes, crumbled feta, capers, fresh chopped mint and olive salad or kalamata olives. Gently toss a few more times to combine. Serve and enjoy!
Notes
This salad is great served as a side in the Spring and Summer months!
