Tri-Colour Sweet Pepper Soup - cooking recipe

Ingredients

2 tablespoons unsalted butter
1 Spanish onion (chopped fine, mine was about 3-inch diameter)
2 red peppers (cut into 1/2 inch wide by 1.5 inch long strips. My peppers were about 4 inch across)
2 green peppers (see above)
2 yellow peppers (or orange peppers, see above)
6 cups chicken stock (I use Swanson brand)
1 teaspoon paprika

Preparation

NOTE: Directions are for the original Sweet Pepper Soup. Sometimes, however, I like to \"mix things up\". For my second version, I reduce the chicken broth to 4 cups, add 1 (14 1/2 ounce) can diced tomatoes (I use Del Monte Petite Diced Tomatoes), 1-2 teaspoons of Dijon Mustard, and 1 cup of sour cream. It is a thicker, heartier soup that is equally enjoyable, just different.
Melt one tablespoon of the butter over medium heat in a large Dutch Oven.
Sweat the onions for 5 minutes until translucent and slightly yellow. I keep them covered during this process. If necessary, add additional tablespoon of butter so the onions do not burn.
Add the three different coloured peppers, stirring well, to mix the soft onions and butter with the peppers. Set timer for 15 minutes; every 5 minutes, stir the peppers and onions and \"taste test\" the peppers to YOUR degree of doneness. We really enjoy a very soft pepper so it takes the full 15 minutes to achieve that texture.
Add the six cups of chicken broth and the teaspoon of paprika and stir well, until combined. ( if using the can of diced tomatoes, use FOUR cups of chicken broth and the can of diced tomatoes).
Bring the soup to a boil, reduce down to a simmer and cover. Every 5 minutes, gently stir the soup. Simmer for 30 minutes.
If you choose to make this a richer soup, use an immersion stick blender to blend up the soup until it is coloured flecks of the peppers. Add the sour cream and Dijon mustard, stir well until heated. DO NOT BOIL!
Serve immediately.
