Cook the brown rice: In a medium saucepan, combine the brown rice and water or vegetable stock. Bring to a vigorous boil—you'll see large bubbles breaking the surface and hear a steady, rolling sound. Once boiling, reduce the heat to low, cover tightly, and simmer for 30–35 minutes, or until the liquid is fully absorbed and the rice is tender but still has a pleasant chew. When done, you’ll notice the grains have split slightly and a nutty aroma fills your kitchen. Fluff with a fork and set aside.

Sauté the aromatics: While the rice cooks, heat the olive oil in a large frying pan or skillet over a medium-high flame. Add the diced red onion and cook for 3–4 minutes, stirring occasionally. The onion should become translucent and soften, and you’ll hear a gentle sizzle as it cooks.

Add the garlic and pepper: Toss in the minced garlic and sliced red bell pepper. Stir continuously for 2 minutes. The garlic will become fragrant—you’ll smell its distinct, pungent sweetness—and the pepper will start to soften and release a little moisture, turning a brighter shade of red.

Cook the edamame: Tip the frozen edamame straight into the pan. No need to thaw them first. Stir everything together and cook for 4–5 minutes. The edamame will turn a brighter, vivid green as they heat through, and they’ll give off a light, grassy scent. You’ll know they’re done when they’re tender to the bite but still have a slight firmness.

Build the sauce: In a small bowl or jug, whisk together the soy sauce, rice vinegar, sesame oil, and grated ginger until well combined. The mixture should look dark and glossy, with the sesame oil creating a few tiny swirls on the surface. Pour this sauce over the vegetables and edamame in the pan.

Combine and finish: Stir the grated carrots and shredded red cabbage into the pan. Cook for just 1–2 minutes, tossing gently, until the cabbage begins to wilt slightly but still retains a bit of crunch. The colours will look vibrant—deep purple, bright orange, and green—and the sauce will have thickened slightly, coating everything in a shiny, savoury glaze.

Assemble the bowls: Divide the cooked brown rice among four bowls. Spoon the edamame and vegetable mixture on top, ensuring each bowl gets a generous portion. Garnish with sliced spring onions and a sprinkle of sesame seeds. Serve immediately while the vegetables are still warm and the rice is fluffy.
