Preheat oven to 375°F. Grease or spray a tin for 18 muffins. (Spray them really well!)
In a medium frying pan, brown the sausage over medium high heat. Break it up into small pieces as it browns. Once browned and cooked through, add broccoli and continue to cook until broccoli is thawed. Remove from heat and allow to cool for 5 minutes.
Meanwhile, in a large bowl, whisk together egg whites, eggs, skim milk, cheese, salt and pepper.
Add sausage and broccoli vegetables evenly to each of the 18 muffins tins.
Pour egg mixture evenly on top of the sausage and broccoli. I used a 1/4 cup measuring cup to do this – it works out almost exactly as 1/4 cup in each.
Bake for 20-25 minutes or until puffed up and golden brown. Leave in muffin tin for about 5 minutes before removing and serving.
