Ingredients

• 5 Tbsp Wild Rosemary Infused Olive Oil, divided
• 3 Sweet Onions, cut into ½ rings or petals
• 1 tsp Rosemary Infused Sea Salt
• ½ tsp Sugar
• 1 Tbsp Mediterranean Rosemary Rub & Seasoning, plus more to finish
• ¼ cup Dry White Wine
• 1 Tbsp Prosecco Italian White Wine Vinegar
• 1 Crusty Italian Baguette
• 8 oz Fresh Mozzarella Slices

Directions

1. In a large sauté pan, heat the 2 tbsp oil over medium heat. Add the onions, Rosemary Sea Salt, sugar, and Mediterranean Rub.
2. Cook over medium-low heat, stirring occasionally, as the onions slowly caramelize and reduce, about 50-60 minutes.
3. Turn the heat up to medium-high and add the wine to de-glaze the pan. Stir in the Prosecco Vinegar. Set aside.
4. Preheat the oven to 400°F.
5. Cut the baguette into ¼” slices and arrange on a baking sheet. Drizzle with Rosemary Olive Oil and bake until light brown in color, about 10 minutes.
6. Top each of the baguette slices with mozzarella cheese, caramelized onions, and a pinch of Mediterranean Rub. Return to the oven until the cheese is melted and golden in color, about 10 minutes. Enjoy!
