Heat the olive oil in a medium soup pot. Sauté the onion, garlic, and green peppers over medium heat for about 5 minutes, stirring often. Add red chili powder, mix in well and add stock, zucchini, spinach or kale and tomatoes. Cook for another 5 minutes and add beans, corn, oregano, and cumin. Bring to a boil on high heat. Once it begins to boil, reduce heat to medium low and simmer uncovered for 15 minutes longer. (Simmering uncovered enhances the flavour) Add chopped parsley, sea salt and pepper. Serves 6.
