Any berries. Strawberries, blackberries, raspberries, etc. Limit the apples and pay attention to how other fruit affect you. Sometimes you can have a small amount of certain fruit and it won't mess up your blood sugar but it varies for each person. Watermelon and other melons are high in sugar so very small amounts of those.
As for veggies, I remember celery, lettuce-preferably leafy greens and not iceberg. Limit the carrots, all potatoes and the corn. You can do half a cob of corn sometimes but then you can't have anything else that has high sugar content that day.
Peanut butter you want to have on hand or honey because if your blood sugar drops you need an instant pick me up to raise it and those too are good for that.
Lima beans are high in sugar but other beans are ok. The main thing is you want to eat protein. So much protein balances out a certain amount of carbs and sugars.
It's a pain to get used to but you learn to adapt. My mom has been dealing with it for almost 2 years now and is still figuring things out. I'm constantly searching for new recipes to try that meet the needs, is filling and is still really good.
