Your food choices aren’t that much different to many peoples. They can be tweaked to help your health whilst still appreciated.
Ok. Sausages might be ok but check carbs. They vary a lot. Wise choices mean you keep what you like but keep carbs to a minimum. Grab a handful of packets in the supermarket and compare carbs per 100g. If your preferred spicy ones are high could you buy lower ones and add lower carb spices to them? Bacon. Gammon? Steak? as alternatives maybe with Tabasco or some similar spice?
I’d drop the toast, and if you really can’t only have one slice of the lowest carb one you can find. Tesco do a high protein one. Hovis do hi-low. Waitrose have a low carb one. There are choices out there.
I’ve no idea on the soup carbs but read the labels of your chosen one and some of the others and choose the lowest. The danger here is potatoes in real soups and bulking agents in cup a soups. Compare fresh, tinned and packets and see what flavours are best in which format.
Rice pudding isn’t good. What other desserts might work? You like cream? Try double cream, soft cheese, a sweetener that doesn’t spike you (I’d go for erythritol or xylitol) and maybe peppermint or vanilla essence. Whip it up well til nice and thick and add a few berries. Grate some very dark chocolate over it all. Or look up keto muffins which can be sweet or savoury and made in the microwave in minutes.
Oranges aren’t the worst fruits, but not the best either. Berries definitely, melon maybe are better. Fruit isn’t essential though. Look here for guidance about better and worse choices and see what works for you

Food low carb can still be pleasurable but yes it will be different. As your tastebuds get used to lower sugar they really do pick up new tastes you never noticed before. For a while shopping will take longer whilst you work out the best options but it soon speeds up as you learn the best options.
Is it worth it? Well personally speaking giving my fingers toes, feet,kidneys, heart, arteries and brain a better chance are worth a few sacrifices. Up to you entirely if yours are
And I have to say for someone worried about cholesterol if you currently eat all those sausages low carb won’t be any more fat based than you eat now!
