Instructions:

1. Preheat Oven:

2. Prepare Cauliflower:
- Wash and cut the cauliflower into small florets. Place the florets in a microwave-safe bowl, add a splash of water, cover, and microwave on high for about 5-6 minutes, or until tender. Drain any excess water.
3. Prepare Sausage:
- Slice the Vienna sausages into bite-sized pieces. In a large skillet over medium heat, lightly sauté the sausage pieces until they are slightly browned, around 5-7 minutes. Remove from heat and set aside.
4. Prepare Egg Mixture:
- In a large mixing bowl, whisk together the eggs, heavy whipping cream, salt, and mustard until well combined.
5. Combine Ingredients:
- Add the cooked cauliflower florets and browned sausage to the egg mixture. Stir in ¾ cup of the shredded cheddar cheese, leaving the remaining ¼ cup for topping.
6. Assemble Casserole:
- Pour the combined mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining ¼ cup of cheddar cheese on top.
7. Bake:
- Place the dish in the preheated oven and bake for 35-40 minutes, or until the casserole is set and the top is golden brown. A knife inserted into the center should come out clean.
8. Serve:
- Remove the casserole from the oven and let it cool for a few minutes before serving. Slice into portions and enjoy!
