Frequently Asked Questions
Can I use canned tuna in oil?
For the Dukan Diet, tuna packed in water is recommended because it is lower in fat. If using tuna in oil, drain it thoroughly and check whether it fits your dietary plan.
Why are oat bran crackers used instead of regular crackers?
Oat bran is a key component of the Dukan Diet. It provides fiber, supports digestion, and replaces refined flour with a more nutritious alternative.
Can I make the crackers in advance?
Yes. They stay crisp for several days when stored in an airtight container.
Is this recipe suitable for meal prep?
Absolutely. Prepare the tuna spread and crackers separately, then assemble just before eating.
Can I add mayonnaise?
Traditional mayonnaise is generally not recommended during the stricter Dukan phases. For a creamy texture, use fat-free Greek yogurt or low-fat quark instead.
Can I freeze the crackers?
Yes. Freeze them in a sealed container for up to 2 months and reheat briefly in the oven before serving.
