Apple, White Cheddar & Arugula Tarts

1Preheat oven to 400°. On a lightly floured surface, unfold puff pastry; roll into a 12-in. square. Cut pastry into 4 squares; place on a parchment-lined baking sheet.

2Sprinkle half of each square with cheese to within 1/4 in. of edges; top with apples (2 medium). Fold pastry over filling. Press edges with a fork to seal. Bake until golden brown, 16-18 minutes.

3In a bowl, whisk oil and lemon juice (1 tablespoon) until blended; add arugula and toss to coat. Serve with tarts.
