Cook quinoa according to the instruction on the package. This will take about 20 minutes.
Meanwhile, cut all vegetables.
Heat cooking oil (we used extra virgin coconut oil for its added flavor) in a large skillet or wok over medium-high heat. Add garlic, chili pepper, and onion. Cook, stirring often, until onions are translucent, about 4-5 minutes.
Add carrots and broccoli. Cook, stirring constantly, until vegetables are tender, about 3-4 minutes.
Add red and Chinese cabbage, peas, pineapple and cooked quinoa. Cook, stirring constantly, until heated through, about 1-2 minutes.
Add ginger and soy sauce. Cook, stirring constantly, until heated through, about 2 minutes.
Optional: add chopped spring onions together with ginger and soy sauce.
