In a large soup pot on the stove, heat the stove to medium high.
Saute the minced garlic and white onion and cook until the onion is translucent.
Once the onions are translucent, add the diced jalapeno.
While the jalapeños are cooking, add the juice of two lines to the garlic, onion, and jalapeno mixture.
Add half of the cilantro, reserving the other half for garnish.
Then, add the chili powder, stirring it into the onion mixture, turning it a deep brown.
Include the peeled baking potato cut into 1-inch pieces and the entire bag of roasted corn.
Now, add the vegetable broth and bring the mixture to a boil.
Put the cover on the pot, and reduce the temperature to simmer.
Simmer covered for 15-20 minutes until the potatoes are soft.
Place the plant milk into a blender, and ladle half of the hot soup into a blender.
BE VERY CAREFUL when blending hot soup in the blender. Make sure the top is tight and vented. For extra precaution, use a towel over the top, and blend at a low speed.
Pour the blended soup into the soup pot with the unblended soup and stir to combine.
Ladle into bowls and garnish with the remaining cilantro and jalapeno slices.
