Shiitakes in puff pastry

These taste the best right out of the oven 2 tbsp olive oil
2 cups finely chopped fresh shiitake mushrooms
3 garlic cloves, minced
1 medium bunch green onions, finely chopped
1 tsp minced fresh thyme
1/2 tsp salt
1/4 tsp pepper
1 sheet frozen vegan puff pastry, thawed

Preheat the oven to 400 degrees. In a large skillet heat the oil over medium heat. Add the mushrooms, garlic, and green onions. Season with thyme, salt, and pepper. Cook until the veggies are soft and the liquid has evaporated, about 10 minutes. Remove from heat and set aside to cool.
Unfold the pastry sheet onto a lightly floured work surface and roll into a rectangle about 12 X 15 inches. Cut the pastry into 3 inch squares and press them into the bottoms of mini muffin tins. Spoon about 1 tbsp of the mushrooms into the center of each pastry cup. Bake until golden brown, about 15 minutes. Serve warm.
