2 cups fresh cauliflower florets

1lb (450g) ground beef

5 slices uncooked bacon, chopped

8oz (225g) no-sugar-added tomato sauce

1 tsp garlic powder

¹⁄₂ tsp paprika

¹⁄₂ tsp fine grind sea salt

¹⁄₄ tsp ground black pepper

1 cup shredded cheddar cheese, divided

¹⁄₄ tsp celery seed

1 medium Roma tomato, sliced

1 Spray a 6.5-inch (16.5cm) 1 quart (1l) round soufflé dish with coconut oil cooking spray. Set aside.

2 Add the cauliflower florets to a food processor and pulse until a ricelike consistency is achieved. Set aside.

3 Select Sauté (Normal). Once the pot is hot, crumble the ground beef into the pot and add the bacon. Sauté for 6 minutes or until the ground beef is thoroughly browned and the bacon is cooked through. Press Cancel to turn off the pot. Transfer the beef, bacon, and rendered fat to a large bowl.

4 Carefully remove the inner pot from the base, rinse and wipe dry with a paper towel, and return the pot to the base.

5 Add the tomato sauce, cauliflower rice, garlic powder, paprika, sea salt, black pepper, ¹⁄₂ cup cheddar cheese, and celery seed to the bowl with the beef and bacon. Mix well to combine.

6 Add the mixture to the prepared dish and use a spoon to press and smooth the mixture into an even layer.

7 Place the steam rack in the inner pot and add 1 cup water to the bottom of the pot. Place the dish on top of the rack.

8 Cover, lock the lid, and flip the steam release handle to the sealing position. Select Pressure Cook (High) and set the cook time for 20 minutes. When the cook time is complete, quick release the pressure.

9 Open the lid. Arrange the tomato slices in a single layer on top of the casserole and sprinkle the remaining cheese over top. Replace the lid and let the residual heat melt the cheese for 4–5 minutes.

10 Open the lid, carefully grasp the rack handles, and lift the steam rack and dish out of the pot.

11 Transfer the casserole to a serving plate and slice into 5 equal-sized wedges. Serve warm.

tip To make this recipe dairy-free, substitute 1 cup shredded almond cheese for the cheddar cheese.
