French Onion Bruschetta

1 Heat a large nonstick skillet over medium-high heat. When warm, pour in the olive oil.
2 When the olive oil is shimmering, add the thinly sliced onions to the pan. Season with salt, and stir continuously with a wooden spoon.
3 Let the onions caramelize slowly, constantly stirring so the onions don’t burn on the bottom of the pan. This process should take 20-30 minutes, depending on the heat in your pan.
4 When the onions have browned beautifully, add the beef broth a quarter cup at a time. Stir with the spoon as the onions soak up the broth. Do this three more times. Add the thyme leaves, and remove the pan from the heat.
5 When the onions are cooked through, turn the oven on to its broil setting. Line a baking sheet with a nonstick baking mat or parchment paper, then set aside.
6 As the oven preheats, slice the bread. Place the sliced bread onto the prepared baking sheet.
7 Spoon the onions evenly on top of the sliced bread.
8 Lay down half a Borden® Cheese Swiss Slice, then top with Borden® Cheese Mozzarella Shreds. (There’s no exact amount here – eyeball it!)
9 Transfer the baking sheet to the oven, and broil for 4-6 minutes, or until the cheese has browned and is bubbling.
10 Remove from the oven, and let cool for 5-10 minutes.
11 Sprinkle with additional thyme leaves, and enjoy!
