Preheat large dutch oven or large pot on medium heat and swirl oil to coat. Add onion, garlic, carrots, bell peppers and saute for 4 minutes, stirring occasionally. Add oregano, cumin, salt, pepper and cook for 30 more seconds, stirring frequently.
Add potatoes, zucchini, green beans, corn, green chilies, black beans, tomato sauce and vegetable stock. Stir, bring to a boil and cover. Reduce heat to low and simmer for 25 minutes or until potato is fork tender.
Turn off heat and add lime juice and cilantro. If you like things spicy, add sliced jalapeno now. Stir and let soup sit for 5 minutes. Taste and adjust any seasonings to taste.
Serve hot garnished with cheese, jalapenos, cilantro and tortilla chips, if you wish.
Notes
Store: Refrigerate for up to 5 days in an airtight container.
Freeze: Cool, transfer to an airtight container, leaving some room for expansion, and freeze for up to 3 months.
Reheat: On the stove on low heat, thawed or frozen it just takes longer.
Frozen and other vegetables: Use any your favorites. You might have to add more broth with some veggies.
Adjust sodium: Add less salt and do so in the end if not using low sodium broth and tomatoes.
Diced tomatoes: Use for less red vegetable soup instead of tomato sauce.
