Place the soja granulat in a heat-proof bowl and pour the hot vegetable broth over it, letting it soak for 10 minutes until fully rehydrated.
Drain the soja granulat through a fine-mesh sieve and press firmly with a spoon to remove as much excess liquid as possible.
Peel and dice the sweet potato into small 1/2-inch cubes to ensure even and quick cooking in the skillet.
Heat the olive oil in a large skillet over medium heat and sauté the sweet potatoes for 8-10 minutes until they are softened and slightly browned.
Add the diced yellow onion and minced garlic to the skillet, cooking for another 3 minutes until the onion is translucent and fragrant.
Stir in the rehydrated soja granulat, increasing the heat slightly to develop a crispy texture on the edges for about 5 minutes.
Add the black beans, chopped kale, tamari, smoked paprika, and dried rosemary to the pan.
Season with sea salt and black pepper, then sauté for 3-4 minutes until the kale is wilted and the entire meal is thoroughly heated through.
