Mushroom-Lentil En Croûte w/ Creamy Dill Sauce

“En croute” is a French phrase meaning “in crust.” It is used to describe food that has been wrapped in dough or puff pastry prior to baking. Pepperidge Farms’ puff pastry is vegan but contains high-fructose corn syrup. I used Aussie Bakery puff pastry sheets found at Whole Foods. Or try your hand at making your own with this recipe.
