250 grams of spelled flour
2 eggs
2 cans of tuna in its own juice
Put the tuna with the juice and the eggs in a bowl and puree until a homogeneous porridge has formed. Then stir in the flour.
Spread the dough about 2-3 cm thick on a baking tray lined with baking paper and use a pizza cutter to roll into pieces of any size.
Bake at 180-190°C on the middle rack for 45 minutes. If you want the cookies to be harder and therefore last longer, simply leave them in the oven for an extra 10 minutes.
Hmmmmm... woof!
