Ingredients
a thawed 17 1/4-ounce package frozen puff pastry sheets (2 sheets)
3
tbsp white-wine vinegar
1
tsp chutney (preferably tomato)
6
tbsp extra-virgin olive oil
4
cups mesclun (mixed baby greens; about 4 ounces)
Directions
1.
Discard rind from Brie and cut into 1/4-inch dice. Freeze Brie cubes, covered, until hard, at least 1 hour, and up to 3 days.
2.
In a bowl lightly beat egg. With a 3 1/2-inch round cutter cut out 4 rounds from 1 pastry sheet and fit rounds into four 1/2-cup muffin cups. Fill cups with frozen Brie cubes. With a 2 1/2-inch round cutter cut out 4 rounds from remaining pastry sheet. Brush 1 side of each round with egg and put 1 round, egg side down, onto each filled cup. With a sharp small knife make steam vents in pastry tops. Chill pastries 30 minutes.
3.
Make dressing while pastries are chilling:
4.
In a small bowl whisk together vinegar, mustard, and chutney and add oil in a stream, whisking until emulsified. Season dressing with salt and pepper. Dressing may be made 1 day ahead and chilled, covered.
5.
Quarter tomatoes and cut out seed sections. Cut quarters into thin strips.
6.
Preheat oven to 425° F.
7.
Bake pastries in middle of oven until deep golden, about 25 minutes. Cool Brie en croûte in cups on a rack 5 minutes and lift from cups, keeping upright. Whisk dressing to combine and in a bowl toss together mesclun, tomatoes, enough dressing to coat, and salt and pepper to taste. Serve Brie en croûte warm with salad.
