Heat oil in a medium-sized pan over medium-high heat.
Sauté the garlic and onions and cook until they soften.
Add the chopped carrot, celery, bell pepper, salt, and pepper.
Continue sauteing for about three minutes.
Add the tomato paste, cumin, paprika and cayenne.
Continue cooking for two more minutes --- mixing often to prevent burning the spices (lower the heat if necessary).
Add the rinsed green lentils and mix.
Pour the stock and add the bay leaf.
Cover with a lid and bring to a boil.
Adjust the heat to medium-low, and simmer for twenty-five minutes.
Add the rice and continue simmering for fifteen to eighteen minutes or until the rice is cooked.
While simmering, taste and adjust the seasoning by adding salt and ground black pepper (or any of the spices used).
Remove the pan from heat and transfer your lentils and rice to plates.
Drizzle with olive oil ---- and serve!
