What kind of insulin have you been given, Steve? The only reason I can think of for a type 1 to have a specific diet is if you've been put on mixed insulin (2 injections a day), which is a very old-fashioned treatment for type 1 - if you're on that ask them to change it to MDI! If you're giving yourself 4 injections a day (MDI) then you can eat what you like, you just have to learn to inject the right amount of insulin for it.
I still eat bread, potatoes, rice, pasta, oats, cakes, biscuits, fruit, jam ... um, pretty much everything I ate before. I do stick to granary bread, brown rice, and brown pasta rather than white. The only thing in my diet which the dietician told me was unsuitable for a type 1 diabetic was fruit juice - it sends blood sugar up too fast so it's only suitable as a hypo treatment - but actually I've ended up having more fruit juice than I used to because I have so many hypos! The only things I've cut down on are raisins (I used to eat handfuls of them as a snack, now I eat handfuls of nuts instead) and honey (it spikes my blood sugar so I only eat it if I need it for a cold or sore throat).
I think some of the recipes you've been looking at are aimed either at type 2s who have to be much more careful what they eat, or at people who want to lose weight. If you're not overweight there's no need to diet!
