In a large pot, whisk together soup, water, and milk. Warm over medium heat, whisking occasionally.
Add the remaining ingredients, stir and bring the soup to a boil and serve or let simmer on low heat for 30 minutes or more.
Notes
Add more or less of the ingredients according to preference, i.e., add more water for a thinner soup or more corn for more substance. Chopped celery also makes a nice addition.
For more substance, add an extra 1/2 cup of milk and 1/2 cup of water as well as 1 cup of prepared macaroni and cheese.
