Add the kale to a large bowl. Drizzle with 1 tbsp of the olive oil and season generously with salt. Use your hands to massage the olive oil into the kale leaves in order to tenderise them. Allow the kale to rest for at least 30 mintues.
Preheat oven to 180°C/350°F. Add the pepitas to a large baking sheet and transfer to the oven for 5 minutes, or until lightly browned and fragrant. Set aside.
Add the cooked lentils to a small mixing bowl and add the lemon zest, parsley and remaining 1 tbsp of olive oil. Season with salt and pepper and mix to combine.
To the bowl with the kale, add the sultanas, feta, green onions, red pepper, toasted pepitas and the cooked lentils. Toss to combine.
Pour over the dressing and season with black pepper. Toss until thoroughly combined and the salad is completely coated in the dressing. Serve.
Notes
To cook the lentils, add rinsed, dried lentils to a small saucepan and cover with cool water. Cover and set over high heat and bring to a boil. Reduce the heat to medium-low and allow to simmer until tender, about 10-15 minutes.
