Brown the ground pork in a skillet with sesame oil. Transfer to your slow cooker. I made it in my Crock-Pot and it turned out lovely.
Add soy sauce, garlic powder, onion powder, chili powder, salt, and pepper. Stir to combine.
Cook on low for 4 hours or high for 2 hours.
In the last 30 minutes, add sliced leeks and stir gently.
Prepare the cauliflower mash by steaming cauliflower rice in a separate pot until tender.
Mash the cauliflower with: 1/2 cup cream cheese, softened, 1/2 cup shredded cheddar cheese, 1/4 cup grated parmesan cheese and salt and pepper
Transfer the cooked pork mixture to a baking dish.
Spread the cauliflower mash evenly over the pork mixture.
Top with the remaining cheddar cheese.
Bake in the oven at 180°C (350°F) for about 20-25 minutes until the top is golden brown.
