Directions

1. Either slice the sausage or take it out of its casings. In a large sauté pan with high sides, cook the sausage over medium high heat. If it sticks, add a drizzle of oil. You may not need any if your sausage is very fatty. If your sausage is loose, use a wooden spoon to break it up into smaller bits, each no larger than the size of a grape. Cook until lightly browned and no longer pink, about 6-7 minutes. 

2. Add in the onions, garlic, and red pepper flakes if using along with the sausage and a few pinches of salt. Sauté, stirring frequently, until softened and browned or just starting to caramelize, about 7-8 minutes.

3. Add the mustard greens, kale and baby spinach to the skillet with a few tablespoons of water if the leaves aren’t wet from washing. If all of the greens don’t fit at once, add more gradually as they cook down, making room in the pan for more. Add a pinch of salt to each big pile of greens you add to the pan. 

4. In a large bowl, whisk the eggs, and then add the milk, cream, mustard powder, salt and black pepper. Whisk until smooth.

5. Brush the bottom of a 3 quart or 9x13 inch baking dish with olive olive. Fit pieces of bread into the bottom of the baking dish in a single layer. Scatter half of the filling over the bread, then add the remaining bread on top, then the remaining filling. Pour the entire egg mixture over the top. Push the bread down to soak it with the egg mixture. All of the bread should be moistened but does not have to be submerged.

6. Cover with foil and refrigerate for 6-12 hours or overnight. It never hurts to set another baking dish or a few plates on top of the foil to hold the bread down in the egg mixture.

7. Preheat the oven to 375 degrees Fahrenheit. Remove the foil cover and drizzle the top lightly with olive oil. Replace the foil.

8. Bake covered for 20 minutes. Remove the foil and bake for another 25-30 minutes or until the top is lightly browned and crisp. 

9. Allow to cool for 5 minutes and then serve with hot sauce if desired.
