Add the 2 cups of water and quinoa in a medium sized pot or pan and bring the mixture to a boil.
When the mixture starts boiling, stir the contents and cover the pan with a lid.
Cook in low heat for about 20 minutes or until quinoa is cooked. You should check in between, like after about 10 minutes to see if there is enough water.
Meanwhile dice the tomatoes in medium sized pieces and keep them aside.
Once the quinoa is cooked, add the diced tomatoes and sliced green chilies to the pan.
Also add salt and garlic, mix everything well.
Add the remaining water to prepare the soup, and again bring the mixture to a boil by keeping the pan uncovered.
Once the mixture starts boiling, reduce the heat and cover the pan with the lid and cook for about 6 minutes or until the tomatoes are very well cooked and soft.
After 6 minutes, see if the tomatoes are cooked and blended well with the quinoa leaving a small orange hint to the quinoa.
Add more water if desired so as to reach the desired soup consistency. Easy and tasty vegetarian/vegan quinoa soup is ready to serve, make sure to serve the soup hot for best results!
Notes
Enjoy the quinoa soup as it is for lunch or dinner or snack or serve with steamed vegetables like broccoli or leafy greens or cooked beans like black beans or even chickpeas.
