This is the antithesis of typical soupy potato salads. Crispy spuds, the bitter edge of radicchio, buttery trout, and a tangy dressing create a palate-awakening salad that just begs for social media stardom. And all the flavours will speak to you even at room temperature, so this salad can also accompany you to the office, potlucks, and picnics. (However, it’s best to keep cooked fish chilled.) For a thicker dressing, you can replace 1/4 cup (60 mL) of the kefir with a good quality mayonnaise.
Stash a few tubers of fresh turmeric in the freezer. When frozen, it becomes much easier to grate. Ditto for ginger.
Kefir is home to a robust population of probiotics, potatoes offer up vitamin C, sustainable rainbow trout is swimming in heart-healthy omega-3 fats, and radicchio is a vitamin K stand-out.
Per serving:
Heat oven to 400 F (200 C).
In large saucepan, place potatoes and cover with water. Bring to a boil and heat until potatoes are just slightly tender. Drain and, when cool enough to handle, slice potatoes in half.
Toss potatoes with 2 tsp (10 mL) oil and 1/4 tsp (1 mL) salt. On rimmed baking sheet, spread potatoes out, and roast in preheated oven until tender and crispy, stirring once, about 25 minutes.
Toss radicchio with 1 tsp (5 mL) oil and 1/4 tsp (1 mL) salt. Place radicchio on top of potatoes and heat until leaves have wilted and are browned in a few places, about 4 minutes.
On separate greased or parchment paper-lined baking sheet, place trout and bake for 12 minutes, or until just cooked through in the centre. Let rest for 5 minutes. Then peel off skin and open up trout. Gently remove bones in one piece. Then gently break apart flesh into large chunks.
For dressing, in bowl, whisk together kefir, cider vinegar, turmeric, garlic, honey, salt, black pepper, and cayenne. Slowly drizzle in olive oil, whisking constantly.
To serve, divide potatoes, radicchio, trout, peppers, and parsley among serving plates. Spoon on kefir dressing and sprinkle walnuts and capers overtop.
