Preheat the oven to 180°C, 350°F.
Line a baking tray with baking paper and lightly spray it with oil.
Blend the cottage cheese, egg and garlic powder until smooth.
Fold through the almond flour and baking powder until combined.
Divide the mixture into 4 even portions on the tray and flatten them into thin round discs roughly 10–12cm, 4–5in wide.
Bake for 15–18 minutes until golden brown.
Let the thins cool slightly, then fill them with sandwich fillings.
