Mushroom Martian Bites

Directions

1. Preheat oven to 400F.
2. Heat olive oil and butter in a skillet over medium heat. Add shallot/onion and saute until fragrant and translucent. Add mushrooms, Herbes de Provence, and garlic and cook for approximately 5-10 minutes.  If using fresh mushrooms, cook until they release their moisture and reduce by about half.
3. Stir in Parmesan, salt, pepper, nutmeg, and heavy cream, and remove from heat. Allow to cool. Mushroom mixture will thicken as it cools.
4. While the mushroom mixture cools, unfold the thawed puff pastry sheets and place them on a floured board. Roll them out to approximately 12" x 15" rectangles. 
5. Whisk together egg yolks with about 2 tablespoons of water and green food coloring.  (Use enough food coloring to make the yolks really bright green.)  Using a 3" biscuit cutter or a floured juice glass, cut 25-30 puff pastry circles. (Use up scraps by balling them up and rolling out and cutting again.  If they begin to "melt" refrigerate a bit and then roll out.)  Brush one side of circle lightly with egg mixture.    
6. Scoop about a tablespoon of filling into the middle of each circle on the side that you brushed with egg yolk mixture. Fold over into a half-moon shape. Seal with your fingers or a fork.
7. Place your puff pastry half-moons on parchment paper-covered baking sheets, about 1" apart.  
8. Brush tops of puff pastry half-moons with green egg mixture.
9. Bake for 12-15 minutes or until puffed, crisp, and cooked through.
