1 Grease two 12-hole mini muffin pans (1 1/2-tblsp capacity).
2 Using a 6.5cm round cutter, cut out 24 rounds from pastry sheets. Press into pan holes. Refrigerate.
3 Heat half the oil in a non-stick pan. Add mushrooms and thyme. Cook, stirring, until mushrooms are soft. Remove. Set aside.
4 Heat remaining oil in same pan. Add onion. Cook over a low heat, stirring occasionally, for about 10 minutes, or until very soft. Add vinegar and sugar. Stir over a high heat for 1 to 2 minutes, or until caramelised. Return mushrooms to pan. Stir to combine. Season.
5 Divide among pastry cases. Combine eggs and cream in a jug. Pour over filling. Top with feta.
6 Cook in a hot oven (200C) for about 20 minutes, or until golden and crisp. Cool slightly before removing from pan.
