# The Ingredients You'll Need:

→ Beef

01 - 1 lb beef tenderloin, cut into 1-inch pieces
02 - 1 tsp salt
03 - 1 tsp black pepper

→ Filling

04 - 2 tbsp olive oil
05 - 1 medium onion, minced
06 - 8 oz button mushrooms, sliced
07 - 1 tbsp soy sauce
08 - 1 tsp dried oregano
09 - 1/2 cup pitted black olives

→ Pastry

10 - 1 sheet puff pastry
11 - 2 tbsp mustard
12 - 1 large egg, beaten

# Step-by-Step Instructions:

01 - Generously season beef tenderloin pieces with salt and black pepper.
02 - Heat olive oil in a skillet over high heat. Brown half of the beef pieces for 1-2 minutes on each side, then remove.
03 - Preheat oven to 400°F (200°C).
04 - In the same skillet, sauté minced onion and sliced mushrooms over medium-low heat for 10 minutes until softened.
05 - Transfer the sautéed mixture to a food processor. Add black olives and blend until combined.
06 - Unfold puff pastry and cut into 3-3.5 inch squares. Spread mustard on each square, add a spoonful of mushroom filling, then top with a browned beef piece.
07 - Place assembled bites on a parchment-lined baking tray. Brush tops with beaten egg. Bake for 10-15 minutes until pastry is puffed and golden brown.

# Extra Tips:

01 - Ensure pastry edges are sealed tightly to prevent leakage during baking. Serve with your favorite dipping sauce for enhanced flavor.
