Notes
Each of the 8 servings contains approximately 1 Tbsp of dried cranberries, which is the max serving size suggested for one meal. If you are sensitive to fructans, and think you may eat more than 1 serving at a time, decrease the total amount of dried cranberries to 1/4 cup (or use fresh cranberries).
When purchasing cranberry juice read the label carefully. Diet cranberry juices may have added fructose and/or sugar alcohols (e.g., sorbitol, erythritol, etc.)
Only use the green part of the green onions. The white parts contain FODMAPs.
