In a medium pot, heat 0.5 tsp olive oil over medium-high heat and brown the beef cubes on all sides.
Stir in the diced yellow onion, garlic, and ginger, cooking until the onion is translucent and fragrant.
Add the diced tomatoes, ground cumin, 0.125 tsp sea salt, and 0.25 tsp black pepper, then pour in 0.25 cup of water.
Reduce heat to low, cover, and simmer the beef stew for 20-25 minutes until the meat is tender.
In a separate small pan, sauté the chopped kale with the remaining 0.5 tsp olive oil and the remaining 0.125 tsp sea salt until wilted and vibrant.
To make the ugali, bring 0.75 cup of water to a boil in a small saucepan, then slowly stir in the white cornmeal.
Continuously mash and turn the cornmeal against the sides of the pot with a wooden spoon until it forms a thick, smooth, and firm dough.
Serve the beef stew and sautéed kale alongside the warm wedge of ugali.
