I think you can have:
1 off slice from 6 pack of Sainsbury's mellow Lancashire, or Double Gloustershire, or Red Leicester
1 x 28.5g Leerdammer Chs slice
1 x 30g Marks and Spencers Cheese Slice Mature or Mild
1 x 30g Tesco Mature Chedder
There's a whole range of full fat cheeses that you can have 28g of and 42g of reduced fat. Also triangles (although I hate those!!) and soft cheese. Maybe worth joining on line again for a while as there have been quite a few additions recently.
Good luck x
