Step 1: Heat olive oil in a large stock pot over medium-high heat. Cook onion and garlic until lightly browned, about 5 minutes. Stir in tomatoes, broth, vinegar, sugar, and red pepper flakes. Whisk in peanut butter. Simmer, uncovered, for 15 minutes.
Step 2: Add rice to soup and stir. Reduce heat, cover, and simmer 25 minutes, or until rice is tender. Garnish with chopped roasted peanuts, if desired.
