Bring a big pot of water that has been salted to a boil. Add pasta and cook until al dente. Drain, rinse with cold water, and set aside.

Massage chopped kale with a drizzle of olive oil for 2 minutes to soften the leaves and reduce bitterness.

Dice cucumber, halve cherry tomatoes, slice onion, and prepare olives. Place them in a large mixing bowl with the kale.

In a small bowl, whisk together olive oil, lemon juice, garlic, oregano, salt, and black pepper until well combined.

Add pasta and vegetables together in a large bowl. Pour dressing on top, toss well, and sprinkle with feta cheese before serving.
