01 - Preheat oven to 425°F. Line a baking tray with parchment paper.
02 - Toss halved potatoes and chickpeas with olive oil, salt, pepper, and minced garlic. Spread evenly on the baking tray and roast for 25–30 minutes, stirring halfway, until potatoes are crispy and chickpeas are golden.
03 - In a saucepan, add rinsed quinoa and 2 cups water. Bring to a boil, then reduce heat to low, cover, and simmer for about 15 minutes, or until water is absorbed. Remove from heat and let sit, covered, 5 minutes. Fluff with a fork.
04 - In a small bowl, whisk together gochujang, soy sauce, sesame oil, rice vinegar, maple syrup, and water until smooth.
05 - Heat a large skillet over medium heat. Add sliced red onion and sauté for 2–3 minutes until softened. Add the roasted potatoes and chickpeas. Pour in the gochujang sauce and toss to coat. Cook for another 2–3 minutes until everything is heated through and well-glazed.
06 - Divide quinoa among bowls, top with the gochujang potatoes and chickpeas mixture, sprinkle with sesame seeds and sliced spring onions.
