Hi and welcome
As others have said everyone has a different diabetic journey, as each body reacts differently to various foods. The best way to find out is with a Monitor, recording immediately before and 2 hours after first bite of a meal. The goal is to keep the increase below 3 mmol. If you also keep a food diary at the same time, you will soon work out what causes your blood glucose to spike. For example, I can get away with a small slice of wholemeal from a 400gm loaf, to have with my poached egg. But I can't take rice, pasta or apples! Other people will have different reactions. I monitored my carbs and cals with an app - there are several on the market, like MyFitBit and Nutracheck. When I was diagnosed, getting one was the first thing I did, and I plan in advance each day so know exactly where I am. I just monitor for new foods these days.
Carbs are a tricky thing. Some people are very sensitive and follow a very low carb diet. I experimented between 50gm and 130gm a day, settling on around 90gm +-15gm. It is impossible to cut out carbs, as even the humble lettuce has carbs. In general vegetables grown above ground are good to eat. Those below ground, like potatoes, parsnips etc are best restricted or substituted.
Cauliflower is my new best friend, riced or mashed. I sometimes top it with a sauce made from the cooking liquor and grated cheese (my brother's recipe). Then I have a selection from runner beans, green beans, broccoli, asparagus, kale, Brussels, spinach, Spring greens, cabbage, squash, celery, leek, onions, peppers, courgettes, tomatoes, swede, a small portion of carrots or sweet potato. That covers 2/3 of a dessert plate (10") and the other 1/3 is protein. You can get courgetti or boodles for pasta, and there are now some zero carb options. I haven't tried them so can't comment.
For me diabetes was an opportunity to try out lots of new things, make a lot of my own soups, try lots of different herbs and seasonings, and use my slow cooker. I've posted quite a few meals on the Food/Recipes section of the Forum, and the thread "What did you eat yesterday" has lots of ideas and pictures. For example, today my meals are: Breakfast, Mushroom and cheese omelette; Lunch: Salad with a couple of slices of corned beef and lemon/black pepper dressing; Dinner: One pot chicken and vegetable casserole done in the slow cooker. It comes to 1100 cals and 48gm carbs, so I have a few carbs to play with. I'll probable have a lime and soda. I checked the soda water and it does not have sweeteners. I don't drink, so I don't know if soda water would go with gin!!!
I make a chickestrone soup, where I substitute cooked chicken for pasta, and throw in carrot, celery, onion, cabbage, leek, squash, green beans, cabbage, haricot beans and tomatoes, with my home made chicken stock and some Italian herb seasoning (and any other left over veggies lurking in the fridge). A 250ml serving is 250 cals and 25gm carbs. Another soup I make with celery, onions, yellow and green peppers, butter beans, sweetcorn, chicken stock, a little skimmed milk and sage. A 250ml serving is 160cals and also 25gm carbs. The beans in both are the source of fibre. For a quick easy meal, take a pack of Mediterranean veggies, top with two or three skinless, boneless chicken thighs dusted in chicken seasoning, and roast in the oven - it will serve 2. It also works with a firm fish dusted in fish seasoning, which goes on half way through the cooking time.
So meals are never boring - in fact I'm having a cooking session today. Best wishes
