I was introduced to this Soup by my lovely Finish friend in Stockholm. She got the recipe from all recipes: http://allrecipes.com/recipe.... Mine is adapted from hers.
The biggest thing I changed in this recipe was the rice. Instead of cooking it with a soup I pre-cook it mostly because brown rice takes years to cook literally!
Heat oil in a large stock pot over medium heat. Cook Onions and red peppers until lightly brown and tender. Stir in garlic when almost done to prevent burning. Stir in tomatoes, vegetable broth, pepper and chili powder. Reduce heat to low and simmer uncovered for 30 minutes.
Stir in the pre-cooked rice, cover and simmer another 5-10 minutes. Stir in peanut butter ( you can put as much or as little as you desire but I prefer much).
