This was a very fast meal to put together; easily on the table in less than 30 minutes. I started the onions and sausage in the pot and then chopped the carrots and celery while they were cooking. Just a note about the red pepper flakes. Use the smaller amount initially, as it will enhance the stew and add a depth of flavor while not adding much heat. Adjust as desired for your own taste.
I preferred the lesser amount of heat, while my husband and oldest son very much enjoyed it with the additional pepper.
