Preheat oven to 350° F .
Steam broccoli until tender (about 3 to 4 minutes in microwave/stovetop).
Place broccoli, soup stock, oil and lemon juice in a blender or food processor and process to a smooth purée.
Place rice and cheese in an ovenproof dish. Pour broccoli mixture over the rice and cheese. Toss mixture gently to blend ingredients.
Place in oven for 15 minutes or until heated through and the cheese is melted. (Instead of using the oven, you can heat this dish in the microwave for 3 minutes, stir, and cook 3 more minutes)
