If you want to consider eating fewer carbs - your meals look very high in carbs for me - you'd need to talk with your diabetic nurse/team first to check if any of your meds need to be reduced.
To note,
I don't eat wholemeal bread - it has almost the same carbs as white bread, I don't eat pastry unless it is fake pastry made with ground almonds and baked potatoes are off my list too.
If I want bread I may have a small slice from a seeded loaf now I'm in remission, before only 90-second bread made with ground almonds.
Instead of potato I'd have mashed cauliflower sometimes mixed with a little butternut squash or kohlrabi.
But I have a few fresh raspberries with full-fat Greek yogurt or a low-carb crumble (almonds again) with rhubarb or gooseberries with real egg custard (no flour) or double cream. Plus a couple of squares of 85% chocolate at bedtime. So plenty of nice tasting foods around to replace the carbs!
