Ingredients:

• 1 pound beef Tenderloin Steak, cut into 3/4-inch pieces
• 2 tablespoons canola oil, divided
• 1 package (8 ounces) mushrooms, chopped
• 3 tablespoons minced onion

Cooking:

1. In large nonstick skillet, heat 1 tablespoon oil over medium-high heat. Add mushrooms; cook 2 to 3 minutes until tender and all liquid is evaporated, stirring often. Stir in onion, thyme, 1/4 teaspoon salt and 1/4 teaspoon pepper; remove from heat and set aside.
2. Preheat oven to 425°F. Toss beef with remaining 1 tablespoon oil, 1/2 teaspoon salt and 1/4 teaspoon pepper.    
3. Spray 24 mini-muffin cups with cooking spray. Unfold puff pastry on a lightly floured cutting board; cut each sheet into 12 (2-inch) squares. Place squares into mini-muffin cups. Brush dough with mustard, then place heaping teaspoon of mushroom mixture in center of dough. Top with steak piece.
