While the potatoes are roasting, prepare the dressing and chop cilantro, red onions, and cucumbers. Also, finely slice the greens from the spring onions.
In a bowl, add Greek yogurt, mayonnaise, harissa paste, maple syrup, lemon juice, paprika, and salt.
Mix it well with a whisk or a spatula.
Cover and store it in the refrigerator.
Now finely chop the cilantro, red onions, and English cucumbers. If you are using the cucumbers with seeds, take out the seeds to make sure the salad doesn't become watery.
Add the finely diced onions and cucumbers to the dressing along with finely chopped cilantro.
Add the crispy potatoes and give the salad a good mix. Use salad spoons to mix the salad properly to make sure the dressing coats the potatoes evenly.
Garnish with crispy bits of roasted potatoes, finely diced spring onion greens, and serve fresh.
The potatoes stay crispy and fresh for 2-3 hours.
