In a Dutch oven cook the green pepper, red onion and garlic in hot oil till onion is tender, but not brown. Rinse lentils.
Add lentils, vegetable broth, and turmeric to the pepper mixture. Bring to a boil. Reduce heat, cover and simmer for 20 to 30 minutes or until lentils are tender and liquid is absorbed.
Stir in tomatoes, peas, olives, and cilantro. Heat through. Season to taste before serving.
