Mix the cream cheese with the garlic powder, onion powder, black pepper and cheese. Spoon 1 tbsp of the mix onto a little piece of greaseproof paper and place another down on top and flatten to make a rough circle. Repeat with the rest of the mix and set aside. You should have 6 disks.
Mix the jalapenos with the beef and divide into 6 balls.
Get a non-stick pan very hot. Season the two balls with salt and pop in the pan, lay down a piece of greaseproof on top, and press down with a heavy pot. Leave for 10 seconds then remove the pot and the paper. Season this side and flip the burgers. Lay a cheese 'slice' on each, then cover with a lid. After 15 seconds, remove the lid, combine your patties. Build your burgers!
