Cheesy Broccoli and Cheddar Stuffed Sweet Potatoes

1. Preheat the oven to 400°F (200°C). 2. Prick the sweet potatoes with a fork and place them on a baking sheet. 3. Bake for 45 minutes or until tender. 4. While the sweet potatoes are baking, steam the broccoli florets until tender. 5. Once the sweet potatoes are done, cut them in half and scoop out some of the flesh to make a 'bowl'. 6. Mix the scooped out sweet potato flesh with the steamed broccoli and shredded cheddar cheese. 7. Stuff the sweet potato 'bowls' with the mixture. 8. Return the stuffed sweet potatoes to the oven and bake for another 10 minutes, or until the cheese is melted and bubbly.
