In a large pot or dutch oven, add the finely diced onion and olive oil. Saute for about 5 minutes.
Add in the minced garlic and diced bell pepper. Saute for about 3 extra minutes, then add in the corn and saute an additional 2 or so minutes.
To the pot, add all remaining ingredients except lime juice.
Stir everything well to combine and bring to a boil. Reduce heat to low, cover and let simmer for about 20-25 minutes, stirring occasionally.
Transfer 2 cups of soup to a blender and blend until smooth.
Transfer back to the pot and stir to combine. Stir in the lime juice and optional hot sauce. Taste and adjust flavors as desired, and/or add more broth to thin it out if you like.
Serve and garnish with tortilla strips, chopped cilantro, fresh lime juice, avocado and/or vegan cheese.
