Combine 2 tablespoons gochujang, 2 tablespoons gochugaru, 2 tablespoons brown sugar, 1 tablespoon sesame oil, ¼ cup water, and 1 teaspoon kosher salt in a glass mixing bowl and whisk until smooth. Taste and adjust the seasoning to your preference.
Sauté the onion and garlic:
Heat 2 teaspoons neutral oil and 1 teaspoon sesame oil in a wide pot over medium heat. Once hot, add the sliced onion and sauté for 5 to 7 minutes until it begins to soften. Add the garlic and sauté for 1 minute until fragrant.
Simmer the chickpeas:
Add the drained chickpeas, minced ginger, the prepared gochujang sauce, and 1½ cups water. Bring to a boil. Reduce the heat to low and simmer, uncovered, for 15 to 30 minutes. Taste and season with salt if needed.
Cook the greens:
Add the chopped baby bok choy to the pot and simmer for 5 minutes until bright green and just wilted. Taste and season once more before turning off the heat.
To serve:
Ladle the chickpeas and greens over cooked rice and finish with sesame seeds and a pinch of gochugaru if desired. Enjoy!
