Heat 1 tablespoon olive oil in a saucepan and add the rice. Stir and coat the rice with the oil, and cook for 1 minute. Add the black pepper and the vegetable stock and bring to a boil. Reduce heat to a low simmer and cover. Cook the rice for 50 minutes, until liquid is absorbed. Let stand for 10 minutes and stir in the cheese.
When the rice is almost done cooking, bring a pot of salted water to a boil and add the green beans. Cook for 3-4 minutes then drain, and rinse under cold water.
Heat the remaining oil in a skillet and add the green beans, chickpeas, and kidney beans. Season with the salt and heat over medium heat until heated through. Serve the beans alongside the rice.
