Ingredients
- Ingredients
- 400 grams Puff pastry dough
- 4 red onions
- 1 handful Lettuce (mixed, such as arugula, Romaine)
- 100 milliliters balsamic vinegar
- 2 Tbsps olive oil
- salt
- freshly ground peppers
Preparation steps
Using a round cookie cutter, with a diameter of about 12 cm (approximately 5 inches) cut out 4 circle from the pastry.
Peel and halve the onions and thinly slice into wedges, not quite cutting through to the end, so that the onion half remains in one piece.
Bring vinegar to a boil and reduce slightly, stirring occasionally.
Drizzle pastry dough circles with olive oil, then top with 2 onion halves on each circle. Drizzle with half of the reduction. Place on a parchment paper-lined baking sheet and bake in preheated 200°C (approximately 400°F) oven for about 10-15 minutes, until golden brown.
Rinse and spin dry the lettuces and arrange on serving plates. Place a tart on each plate and drizzle with remaining reduced balsamic. Season with salt and pepper. Serve immediately.
