Ive done this quite a few times, I take loads of fruit and also mini veg (baby tomatoes, baby, corn, snap peas/mange tout, carrots, whatever). Thats your superfree taken care of, then you can have whatever you fancy with kettle-wise. Cous cous or bulgar wheat are great cos they're free and dead easy, you just pour the water over. Take a little bit of chilli sauce or whatever to mix in if you like.
You can do the mugshot thing if you like but personally I dont do them as I dont think theyre very healthy or nice, personal preference.
You can always pop out in the week and buy more, most days I would pop into the supermarket and get more fruit & veg, prepacked salad or fruit and a few slices of lean meat or Quorn slices or whatever to go with it. Yoghurts too.
Better doing this for dinner though as others have said Jurys Inn is dead easy for breakfast, they have tons and tons of fruit available. If you want cooked they have beans, mushrooms, tomatoes etc, you can cut the fat off the bacon, they have skimmed milk available. Im not entirely sure if anything is cooked in fat but I would guess not as they have to be open to such a mass market, you can always ask anyway. Oh and take some laughing cow light to use as low fat spread for your (wholemeal) toast!
