Swiss Cheese Onion Crostini

Ingredients:

1. 2 tablespoons extra-virgin olive oil
2. 2 yellow or white onions, very thinly sliced (about 3 cups)
3. 1 teaspoon dried thyme
4. 1/4 teaspoon fine sea salt
5. 1 large baguette, sliced on the diagonal into 12-16 slices, about 1/2-inch thick
6. 2 tablespoons Dijon mustard
7. 2 cups grated Gruyère cheese
8. 1/4 teaspoon ground black pepper

Method: 

1. Preheat the oven to 425°F. 
2. In a large skillet, heat oil over medium-high heat; add onions. Cook at least 3 minutes before stirring (onions should start to brown before you move them around). Continue to cook, stirring only occasionally, about 20 minutes, until onions are soft and well browned. 
3. Add thyme and season with salt and pepper. 
4. Spread bread slices with a little mustard. 
5. Divide onion mixture evenly over bread slices then top each with cheese. 
6. Place on a foil-lined baking sheet; bake 10 minutes or until cheese is melted.
