Now because everything else we are adding is cooked and just needs to be brought up to temperature turn the heat to medium-low. Add the minced chicken (this can be canned, rotisserie, leftover, white meat, dark meat, chicken you cooked just because you wanted to make soup... Chicken). Then add the chopped mushrooms. I like using the ugly little canned mushrooms for this soup because it keeps soup prep to less than ten minutes. Stir! You thought I was going to say whisk didn't you....
