I stumbled on this recipe in a Taste of Home Soup Cookbook. You'll just love the spice and touch of sweetness from the secret ingredient, pears! I make a huge batch when red peppers are cheap, it freezes beautifully.
In a large pot saute garlic and onion in butter till tender. Add potatoes, red peppers and broth. Bring to boil. Reduce heat, cover and simmer 15-20 minutes till veggies are tender. Remove from heat. Add pears, let cool.
In a blender, cover and puree in batches. Return to pot, add cayenne and heat through. Enjoy!
