Roasted Red Pepper Soup

Quote from Mike: "This soup is banging". I think that says it all.

1 jar roasted red peppers
1/2 sweet onion, chopped
2-3 cups vegetable broth
2 tbsp olive oil or butter
1/4 cup half and half
salt and pepper
Parmesan cheese
cayenne pepper

Saute onion with butter or olive oil in a pan, approx. 8-10 minutes. Drain red peppers, chop, then place in pan, seasoning with salt, pepper and a dash of cayenne. After 2-3 minutes, add broth, then bring to a boil. Cover, reduce heat, cook 15-20 minutes. Pour soup into blender and blend until smooth. Put back in pan, then add half and half. Serve topped with a little Parmesan cheese or scallion.
