Make the sauce. In a large skillet over medium-high heat, melt the butter. Add the sesame oil, ginger, and garlic and sauté until aromatic. Whisk in the soy sauce.

Cook the veggies. Add the broccoli to the skillet followed by the cabbage and, finally, the kale. Pour the water over the veggies and put a lid on the skillet. Cook for 5 minutes or until the broccoli is fork-tender, stirring every couple of minutes.

Serve. Serve warm garnished with sesame seeds.
