Heat the canola oil in a skillet over medium high heat. Brown the ground sausage in it until cooked through. While it cooks, flavor it with the salt and Worcestershire sauce. Once it is done, take the pan off of the heat and set it aside to cool a bit. Take an 8 x 8 pan and liberally grease it with cooking spray.

Layer the 3 slices of bread in the baking pan to form a bottom layer. The third slice can be cut to fit in around the other two slices so that the whole bottom is covered. Layer the cooled sausage mixture evenly on the bread. Sprinkle the cheddar evenly on top of the sausage. Combine the eggs, milk and parsley in a bowl and whisk them together until smooth. Pour that mixture over the layers to enrobe them. Cover the casserole and let it sit in the refrigerator overnight.

In the morning, preheat the oven to 375. Let the casserole bake for 45-50 minutes. The cheese should be bubbly and the eggs should be set. Allow to cool for a few minutes, then serve immediately! This can easily serve 4 people when cut into quarters.
