Mustardy Grilled Cheese

• For the mustard greens
• 1 bunch mustard greens, cleaned and roughly chopped
• 3 tablespoons olive oil
• 1 pinch salt and pepper, to taste
• For the sandwiches
• 8 tablespoons unsalted butter, room temperature
• 8 slices thick-cut bread (I prefer brioche)
• 6 tablespoons stoneground mustard
• 24 to 28 slices sharp cheddar cheese
• 1/4 red onion, thinly sliced

1. First, cook your mustard greens. Clean and trim the leaves, then heat 3 tablespoons of olive oil in a large pan over medium-high heat. Add in the greens and stir until wilted, about 5 minutes or so. Season with salt and pepper to taste, then remove from the pan and set aside. Wipe out the inside of the pan with a paper towel.
2. Butter both sides of each slice of bread, then reduce the pan's heat to medium and add in 4 slices of bread at a time (or however many slices your pan can hold) and toast one side. Flip two of the slices of bread (so that the toasted side is up) and add 1 1/2 tablespoons of mustard, followed by 3 to 4 slices of cheese, 1/4 of the mustard greens, a few slices of red onion, and an additional 3 to 4 slices of cheese. Top these two pieces with the other two slices of bread, placing them toasted side-down onto the cheese. Use a spatula to press down on the sandwiches, then cover the pan lightly and cook for 3 to 4 minutes.
3. Remove the cover, flip the sandwiches, and cook for another 3 to 4 minutes, pressing down again with a spatula. Remove the sandwiches from the pan when the cheese is gooey and melted, then finish with the remaining sandwich ingredients (you can keep the sandwiches warm in a 250u0b0 F oven). Serve warm.
