In a casserole dish, brown the minced onions and garlic without browning.
Add the other vegetables and quinoa, sprinkle with cumin. Stir well and moisten with the broth.
Simmer for 30 minutes.
When the soup is cooked, break the eggs one by one and pour them into the soup, beating vigorously between each egg, so as to obtain a fluffy consistency (if not, proceed in the same way with the tofu).
