Cut the cauliflower into small florets. Add to a food processor. Process until it resembles rice.
Melt one tablespoon of butter in a large frying pan over medium heat. Add the cauliflower and season with salt and pepper to taste. Stir well and cook for 8-10 minutes.
Add the heavy cream and half of the shredded cheddar. Stir all well and reduce the heat to low. Continue to cook for 3-4 minutes or until the cheese has melted.
Transfer the mixture to a baking dish (13×7 inch). Using a wooden spoon or a spatula, spread the cauliflower mixture as evenly as possible. Set aside.
Melt the remaining butter over medium heat. Add the ground beef and season with salt and pepper. Mix well and cook for 10 minutes, stirring occasionally.
Preheat the oven to 400°F/200°C. Spread the meat evenly over the cauliflower layer. Top with the remaining cheddar. Drizzle ketchup and mustard over everything and bake for 10 minutes.
When done, remove from the oven and cool for 10 minutes before serving. Cut into six equal pieces and optionally serve with some more sugar-free ketchup. Serve immediately.
