Pre-heat oven to 375 degrees
Choose a large/deep casserole dish to grease.
Peel and cube all the sweet potatoes and butternut squash. Make the cubes as small as you'd like. Just be careful not to cube them too tiny unless you want more of a 'mashed' type casserole.
Add the sweet potatoes and butternut squash into the greased casserole dish. Drizzle olive oil on top. Add in shallots, salt, pepper, and cumin. Mix well and cover with a lid.
Bake for 45-60 minutes or until all vegetables are soft and tender.
While the casserole is baking cook ham or bacon, drain, and set to the side.
Once the casserole is done baking remove from the oven, add in ham or bacon, frozen kale, and sprinkle cheese on top.
Bake uncovered for another 10 minutes or until the kale has softened and the cheese has melted.
This makes a great side dish or main course!
