Heat oil in a large saucepan over medium-high heat and add onions, ginger, garlic, cumin seeds, and green cardamom.
Cook until onion is soft, about 3-5 minutes
Add tomato, and remaining spices, turmeric and garam masala.
Let the masala cook until the tomatoes are soft, about 5 minutes.
Add in the vegetables and let them cook with the masala until they are nice and soft.
Once the veggie masala is ready, sprinkle cilantro leaves, green chilies, and mint, as we do traditionally in biryani.
Top it off with cooked quinoa and let it cook on low flame until the flavors amalgamate for 8-10 minutes.
Serve
