Preheat the oven to 375 degrees.
Grease a 9 x 13 casserole dish with cooking spray and set aside.
Add hashbrowns, egg whites, and turkey sausage crumbles to a large bowl. Mix and add desired seasonings.
Pour mixture into the greased casserole dish.
Sprinkle with shredded cheese.
Bake for 30 minutes or until the top is golden and a fork comes out clean.
To portion, divide into 6ths; for a more exact portion measurement, divide total food weight (not including dish) by 6.
Top with hot sauce (if you want) and enjoy!
