Kongbiji jjigae is an old Korean recipe for using up okara, the leftover pulp from making soy milk. Serve this spicy, funky stew with rice for a low-waste meal.
Pour 1 tbsp of oil into a skillet on medium heat. Briefly sauté onion and garlic until aromatic, then add 3/4 cup of drained kimchi. Cook for a few minutes, then transfer this mixture into the ttukbaegi.
Add the kimchi brine, black pepper, soy sauce, okara, and vegan beef. Simmer for 10 minutes, then turn off the stove and let the jjigae cook for another 5 minutes in the residual heat.
