Arrange mushrooms, sweet potato, onion, and kale on a sheet pan. Drizzle with olive oil, season with salt and pepper, toss to coat. Roast until vegetables are tender and slightly caramelized, 20 to 25 minutes.
STEP 3
Heat another sheet pan in the oven. Once the vegetables are almost done, drizzle 3 tablespoons olive oil on it. Spread cold rice over one half and crack eggs on the other half. Bake for 3 to 6 minutes until whites set and yolks are runny.
STEP 4
To serve, divide rice into bowls, place vegetables on top, and slide eggs over. Drizzle with sesame oil and gochujang. Mix before eating, and serve kimchi if desired.
