Place the quinoa, the vegetable broth, the coconut milk, the diced tomatoes, the red curry paste, and the curry powder in a large pot and stir well. Cook on medium heat (without a lid).
After 6 minutes, add the bell pepper, the beans, and the green onions.
After 5 more minutes, add the broccoli. Stir well.
Cook 8-10 more minutes (on medium heat, no lid) or until the quinoa is ready. Season with salt and pepper.
Notes
Not all red curry pastes are vegan, so make sure to check the label.
As the spiciness often depends on the brand, I recommend checking your curry paste first before you add it to the quinoa. Adjust the amount to your personal liking.
Don't worry about not having enough liquid in this recipe. The canned tomatoes, the coconut milk, and the vegetable broth will provide enough liquid to cook the quinoa. You don't have to cook it separately.
