Cut the Oven Café Classic Garlic Loaf into 1/2” inch slices on a bias. Place into the oven under a broiler until lightly toasted.
Heat a medium sauté pan over medium heat. Add the olive oil and garlic. Sauté for 1-2 minutes, until the garlic becomes fragrant. Add the kale and sauté until just wilted. Remove from the heat. Squeeze any excess moisture out.
Spread the mustard on each slice of bread.
Place the kale on each slice of bread. Top with the raclette slices and caramelized onions. Season with salt and pepper.
Place the bread onto a baking sheet with a roasting rack. Place the baking sheet under a broiler for 2-3 minutes, until the cheese is melted and bubbly.
Garnish with the sliced chives.
