Nuts, carrots/veggies dipped in Caesar dressing, salads, cheese, sometimes if my sugars between meals are in the 4s i have some crackers with that cheese and Peanut Butter cookies made with Spenda instead of sugar. Each Cookie turns out being like 4g of carbs, but is such low glycemic index that it hardly raises my sugars at all (well if you eat a reasonable amount lol)
Most times i just have a snack and bolus for it accordingly..
However, in my first 3-4 months i did not eat between meals at all because i hadn't really gotten the hang of adjusting my sugars and insulin yet so i too just starved OR ate huge meals OR just ate whenever my sugars got low enough to allow for it haha
