Grilled Cheese Sandwich with Sautéed Leeks and Bacon

Instructions

1. 1

   In a non-stick skillet over medium heat, soften the leek in 2 tbsp of the butter for 5 minutes. Add the arugula and cook for 1 minute. Season with salt and pepper. Set aside in a small bowl. Clean out the skillet.

2. 2

   Spread one side of each slice of bread with the mustard. Divide the leek, cheese and bacon among 4 slices of bread. Close the sandwiches with the remaining bread. Butter the outsides of the sandwiches with the remaining butter.

3. 3

   In the same skillet over medium-low heat, brown two sandwiches at a time, about 3 minutes per side, pressing the sandwiches down with a spatula until the cheese has melted. Cut the sandwiches in half, if desired.
