So you're on insulin, but no-one talked to you about nutrition? Can I then assume you're on a fixed dose? Because I can go over your food choices, but if you cut the carbs, you are likely to need to lower your dosage. So be forewarned, some adjustments might need to be made. Test, test, and test again. Also, what I can tolerate may not be something you can, and vice versa, so always check whether a meal agreed with you. We can make educated guesses on what is likely to spike someone due to the carb content, but we won't know by how much. A regular white roll can up me to 22, for instance, someone else might have a blip to 8,5... We're all different, which is why we're so adamant on the testing thing.

Everything I've deleted from your list seems fine to me, but I'm not always familiar with your brands.
1 x chickpeas mixed with a few baked beans would be too starchy/carby for quite a few here. Some can get away with it, some can't. Certainly worth checking. test before the meal and 2 hours after the first bite. You're looking for a rise of no more and preferably less than 2.0 mmol/l.
100mls cranberry juice with water can hit the system with a hard spike, 100mls of unsweetened juice containing 13 grams of carbs which are quickly absorbed due to their liquid state.
1/4 of an orange isn't much, but personally I wouldn't go there.
Handful of ;type of potato.;Or Quinoa, ;Wholemeal rice or wholemeal pasta. All of these are high in carbs. I'll steal a fry off my husband every now and again, but that's as far as that goes. Haven't had the rest of any of those these past 7 years. Really worth testing to see how you respond. Possible alternatives: cauliflower or broccoli-rice, konjac noodles.
Afters Forest fruits, with no sugar tog; stewed apple or pear, no sugar, kvarg mixed with yog. fruit salad. If with forest fruits you mean berries, those are usually fine in moderation. And apple or pear would spike me, though if you have it with yog you might slow down the spike with the fats in that. Fruit salad I wouldn't dare touch, especially if there's stuff in there like grapes and the like... Those are kryptonite.
pomegranate seed might be a bit much, depends wholly on how much you have. A whole one would be about 25 grams of sugar.
mini pork pie might be problematic due to the crust and fillers used.
Or something on toast <-- regular toast or the excellent low carb bread you mentioned before?
lo sugar cereal, no idea which one it is, home made or a keto brand, but usually, cereals are grain or corn based, and those'll spike whether there's sugar added or no.
John Burts sour cream chips, ....which are almost 60 grams of carbs per 100 grams. That's a lot.
50ml lowest sugar ice cream Which brand would that be? Oppo and such'd be absolutely fine.
satsuma, small apple ...are both too sugary for my taste, but might not be for you.
Wetherall lo sugar toffee (questionable on carbs ?) If you mean Werthers, there are some carbs in there, but those are from artificial sweeteners that don't actually end up in the bloodstream, they go out the backdoor like they came in, ergo undigested. Which is why it can bring on the runs, on top of some types being toxic to gut flora... Don't overdo it and you should be fine though.
Hope this helps some! In the end, you choose how to handle this, just be very careful if you make changes, what with the medication you're on. Right now you eat in a day what I probably don't put away, carb-wise, in a full week. But that's what works for me, it might not be the case for you.

Good luck,
