Preheat oven to 450. Poke holes with a fork all over sweet potatoes. Roast potatoes for 50-70 minutes. In the meantime, in a large skillet heat olive oil on medium heat. Add garlic, after about 30 seconds, add broccoli, red pepper flakes & kosher salt. Saute 5-7 minutes. Drain & rinse beans. In a blender add beans, water, 1/2 c shredded cheese, and kosher salt. Blend until well combined.
Cut centers off from potatoes. Drizzle with olive oil (optional) and salt. Place cheese mixture, then broccoli then chicken (if using) then top with the rest of the cheese. Bake 5-7 minutes or until cheese is melted.
