Baked Roast Beef and Brie Sliders

Directions

1. Begin by preparing your caramelized onions. Heat olive oil, in a large skillet, over low heat. Add the onions and salt. Cook on low, stirring occasionally until the onions soften and begin to caramelize about 20-25 minutes. Drizzle in balsamic and stir to combine. Cook for an additional 5-10 minutes. Remove from heat and set aside.
2. Preheat your oven to 350 degrees F. In a small bowl, whisk in the olive oil, mustard, honey, garlic powder and a dash of salt and black pepper.
3. In a 9x13-inch baking dish, brush two tablespoons of the olive oil mixture on the bottom of the dish. Take the bottoms of your rolls and place them in the baking dish. Layer on baby spinach, roast beef and brie cheese. Top with caramelized onions. Place the tops of the rolls on top. Brush the remaining olive oil mixture directly on top of the rolls.
4. Cover the dish with foil and bake for 15-20 minutes or until the cheese has melted. Remove from heat and serve immediately.
