Heat the olive oil in a large skillet over medium heat. Add the turkey sausage. Cook until the turkey is slightly browned and no longer pink, breaking the sausage into small chunks. Cook for 6-8 minutes. 

Add the sweet potatoes to the skillet and continue cooking until they are soft and slightly crisp around the edges, approximately 10-12 minutes.

Add the broccoli and stir to combine. Cover and allow the broccoli to steam for 2-3 minutes.

Remove lid and sprinkle the shredded Mozzarella on top. Cover for another 1-2 minutes or until the cheese is nicely melted. Remove from heat and serve immediately.
