Prepare the 2 green peppers. Cut off the top and remove the seeds and ribs. Rinse and dry the pepper, setting it aside.
In a large pot heat the vegetable broth on medium-high heat. Saute the garlic and onion for 3 minutes or until the onion is softened.
Add the tomatoes, lentils, rice, water, paprika, cumin, chili powder and crushed red chilies. Bring to a boil; then reduce heat, covering the pot and simmer for 20 minutes or until rice is cooked and the lentils are soft.
Add the yellow or orange diced pepper and simmer uncovered for 3 minutes.
Place the hollow green pepper on a lined-baking sheet and stuffed the peppers with the rice/lentil mixture. Put on the top of pepper and cook in a preheated oven (400°F).
The oven rack should be placed in the middle of the oven. Cook for 10 to 15 minutes until the green pepper starts to soften.
