In a small, dry skillet, brown the coriander seeds, stirring and shaking until they become fragrant and lightly brown. Transfer to a mortar and pestle and grind. Keep aside. Or use 1 tablespoon of ground coriander.
In a soup pot, heat up the olive oil over medium heat. Add the onion and garlic and sauté until translucent, about 2-3 minutes.
Add the tomatoes, broth, potatoes, roasted chiles, ground coriander, and oregano. Add salt and pepper to taste. Bring to a boil, lower the heat to a simmer, and let cook for about 12-18 minutes, until the potatoes are fork-tender, but not too soft.
Add the green beans, the red kidney beans, and the corn. Simmer for 5 minutes more. Turn off the heat, add the lamb’s quarters or spinach. Let wilt for a few minutes and serve with fresh cilantro. Bon appétit!
