01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Toss halved potatoes and chickpeas with olive oil, salt, pepper, and minced garlic. Spread evenly on the baking sheet. 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 15 minutes until water is absorbed. Remove from heat and let sit covered for 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 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.
