01 - Whisk together miso paste and 2 tbsp water in a small bowl until completely smooth. Set aside for later use.
02 - Heat olive oil in a large skillet over medium heat. Add sliced onion and sauté for 2 minutes until softened and translucent.
03 - Add minced garlic and smoked paprika to the skillet. Cook for 30 seconds, stirring constantly to prevent garlic from burning.
04 - Increase heat to medium-high. Add chopped kale in batches, tossing continuously to wilt and accommodate all leaves. Sauté for 3–4 minutes until kale is tender yet remains vibrant green.
05 - Pour the prepared miso mixture over the kale. Toss thoroughly to coat leaves evenly. Continue cooking for 1–2 minutes to allow flavors to meld together.
06 - Season with chili flakes, black pepper, and additional salt if desired. Remove from heat immediately.
07 - Drizzle with toasted sesame oil and sprinkle sesame seeds evenly over the dish before serving.
