In a medium saucepan, bring water to a boil. Add quinoa and reduce heat to low. Cover and simmer for 15 minutes or until the water is absorbed and quinoa is fluffy. Remove from heat and let cool.
In a large bowl, massage chopped kale with a little bit of salt until it softens.
Add the cooked quinoa, cherry tomatoes, and crumbled feta cheese to the kale. Toss to combine.
In a small bowl, whisk together olive oil, lemon juice, minced garlic, salt, and pepper.
Pour the dressing over the salad and toss gently until everything is well coated.
Serve immediately or refrigerate for later use.
