Our flaky stuffed pastries are a vegetarian main that's easy and elegant -- just add a salad for a complete meal.

Ingredients

2 tablespoons olive oil
1 large onion, chopped
4 packages (5 ounces each) mixed mushrooms, trimmed and thinly sliced
Coarse salt and ground pepper
1 sheet frozen puff pastry (from a 17.3-ounce box), thawed
½ cup reduced-fat sour cream, for serving

Directions

Preheat oven to 425 degrees. In a large nonstick skillet, heat oil over medium-high. Add onion; cook, stirring occasionally, until golden brown, 5 to 6 minutes. Add mushrooms; cook, stirring occasionally, until mushrooms are tender, 4 to 5 minutes. Season with salt and pepper; set aside.
On a lightly floured work surface, roll out dough (still folded in thirds) to a 20-by-10-inch rectangle. Using a pizza cutter or sharp knife, trim edges straight; cut dough into four 10-by-5-inch rectangles. Dividing evenly, mound mushroom mixture on one half of each rectangle, leaving a 1/2-inch border on three sides. Lightly brush border with water; fold other half of pastry over filling, and press edges firmly to seal. With a floured fork, crimp edges.
Using a wide metal spatula, transfer turnovers to a large baking sheet. With a paring knife, cut 3 to 4 small slits in the top of each turnover. Bake until golden and puffed, 20 to 25 minutes. Let cool 5 minutes; serve turnovers with sour cream.

Cook's Notes

Store-bought puff pastry makes quick work of these savory turnovers that require only five ingredients.
