Peel and dice potatoes, chop onion, drain and rinse cannelini beans - leave cans of corn AS IS!
Saute the onions in olive oil until soft and translucent
Add potatoes and corn stock or water - simmer until potatoes are fork-tender
Remove about half of the potatoes & onions into a separate dish then add the beans and one can of corn into the pot
Using an immersion blender, blend the ingredients in the pot until they are a smooth consistency
This is what the chowder should look like after blending
Add the potatoes and onions back into the pot, as well as the last two cans of corn - stir to combine and cook just enough to reheat
Here is the final result. Spoon into bowls and enjoy with a nice piece of crusty bread!
