Preheat the oven to 400°F (200°C).
Meanwhile, rinse and drain the canned beans and corn, dice the onion, bell pepper, and zucchini, slice the olives, and mince the garlic.
Combine all the ingredients in a casserole dish (9x13 inches/ 23x33 cm), stir well, ensuring the rice is evenly covered, and bake covered with a lid for 40 minutes, or until the rice is tender.
Top with the vegan cheese sauce and fresh cilantro (or parsley), and enjoy!
