Of course, you may also use any other cheese you prefer, like mozzarella, parmesan or cheddar.

The pulled pork turns out great if you use pork neck instead of shoulder, too. It may be even better as pork neck usually is a little fattier then shoulder and therefore juicier & more flavorful.

To make it even better, you may prepare & marinade the meat in the morning or one day in advance and let it soak in the seasonings for a longer period of time. Simply let it stand for 1-2 hours or longer instead of 10-15 minutes. If you prepare it a day in advance, put the bowl into your fridge and cover it with cling film.

The seasonings are amazing for marinading  pork chops or spice up some ground beef, too.
In addition, you could use pork loin instead of ham or try it with other cuts.

Serve with any keto friendly side dish you like, e.g. salad, fried / baked vegetables, some eggs or simply a low carb condiment.

The additional egg in the ground beef mixture helps to hold everything together. I didn't do this here, but highly recommend it as the result will be better that way.

Also, deep frying is the best method to cook these, because they get fried more evenly and are done faster.

Serve with any side dish you like - e.g. oven baked broccoli, fried string beans or cauliflower mash. I simply added some low carb ketchup & mayo.

Tip: If you want to go full pro add a layer of "breading" around the ground beef. You could use crunched pork rinds / crispy bacon bits for that.

You probably could skip the meat hammer step if your beef liver pieces already are pretty flat (about 0.5cm / 0.2in of thickness).

If they are way too thick, lay them on the cutting board.
Then, cut from one side with a sharp knife until you nearly reached the end of the other side.
Now, you can simply fold out the pieces and have thinner ones.

At step 3 I used frozen spinach which I thawed & pre-cooked in the microwave for about 3 minutes while beating up the liver:

Of course, you may also use different stuffings.

One idea that I've had was pizza stuffing with tomato paste or fresh tomatoes, mozzarella cheese & Italian / Mediterranean herbs (oregano, rosemary, thyme). Maybe with some additional ground beef, pepperoni, fried chicken or even pulled pork.

If you want to render the kidney fat cut it into small bits or mince it in a food processor.
Then, put it into a pot or big pan on low heat and wait for all the fat to get out while stirring occasionally.

You can see that it's done when there is clear fat on the bottom with crispy bits on top.

Now, you can remove these floating bits by pouring all content through a cheesecloth or fabric into another pot.
When the fat is cooled, pour it into mason jars and keep them in the fridge.

You can check if the pork back is done to your preference by using a meat thermometer.
If the core temperature reaches 70-75°C (158-167°F) the meat is medium-well. If its core temperature reaches 80-85°C (176-185°F) it is well done, but not as tender anymore.

In addition, you may also use the juice from the baking tray to make a delicious gravy sauce or simply pour it over the vegetables you may have made as a side dish.
For a sauce, simply fry 2 onions with butter in a pan (until golden brown), then pour in the meat juice and let everything cook until it is reduced to your desired thickness.
If you don't want to use onions, replace them with 100ml (about 3oz) cream in order to get thickness to the sauce.

The method in this recipe works with nearly any type of meat, but best with cuts that contain fat & some gristle like beef shank or ham hock.

You may also enhance the sauce by deglazing the onions with red wine and let it cook for a minute before adding the meat stock.
