In a large mixing bowl, combine the chopped kale with a pinch of salt. Using your hands, massage the kale for about 2-3 minutes until it starts to soften and wilt slightly. This helps to make the kale more tender.
In a separate small bowl, whisk together the lemon juice, olive oil, minced garlic, lemon zest, and a pinch of salt and pepper to create a dressing.
Pour the dressing over the massaged kale and toss until the leaves are well coated.
Add the grated Parmesan cheese, toasted pine nuts, cherry tomatoes, cucumber, and red onion to the kale. Gently toss everything together to combine.
Taste and adjust seasoning with more salt, pepper, or lemon juice as necessary.
Allow the salad to sit for about 10 minutes before serving to let the flavors meld together.
Notes
Serve the salad in a large bowl or individual plates, garnished with extra Parmesan flakes and a sprinkle of lemon zest on top for an attractive finish.
