Preheat your grill (aka broiler for my US readers)
Place pork scratchings into a food processor and blend.
Add cheese and pulse until combined.
Roll small balls in your hand and press them down on a baking sheet. Be sure to leave plenty of space in between them as they flatten out. I made 20 (and calculated the nutrition info for 20), but as the chips are very filling, you could also make them a little smaller than shown in the pictures above and get around 30.
Place under the grill and wait until they are browned - about 2-5 minutes, depending on your oven. Watch them closely and don't leave the kitchen.
At this stage the chips are VERY soft. Wait until they are cooled down and have firmed up. Then you can either brown them from the other side as well or enjoy straight away :)
Notes
If you use ready-made scratchings, try to choose a brand that uses as little nasties as possible. Store in an airtight container at room temperature for up to 5 days. I do not recommend storing them in the fridge as they will go a little limp.Option to freeze them for up to 3 months!To crisp up the chips, simply put them back into the oven for a few minutes. As soon as they cool back down, they taste as good as new!
