Scrub potatoes and cut into 1/2-inch cubes or wedges. Steam over boiling water until just tender when pierced with a fork. Rinse with cold water, drain, and set aside.
Rinse the kale and remove the tough stems. Cut or tear the leaves into small pieces. Heat 1/4 cup of vegetable broth in a large nonstick skillet and cook the kale. Set aside.
Heat 2 tablespoons of vegetable broth in a large nonstick skillet and add the onion, garlic, dill, and sesame seeds. Cook until onions are translucent.

Enjoy!
