Ingredients
Method
1.Preheat oven to 220°C (200°C fan-forced). Line an oven tray with baking paper.
2.Heat oil in a saucepan on low. Cook onion and thyme 20-25 minutes, stirring occasionally to prevent burning. Stir in vinegar and sugar; cook further 10-15 minutes, until thick and “jammy”.
3.Using a 7cm round cutter, cut out pastry circles. Arrange on tray; brush lightly with egg. Bake 5-7 minutes, until puffed and golden. Cool slightly on trays.
4.Top each pastry round with feta and caramelised onions. Serve.
Red onions produce a slightly sweeter result, but if you don’t have red, use either white or brown.
