A delightful twist on a classic warm sandwich, featuring chicken, mushrooms, spinach, and gooey cheese.
Preheat your oven to 400°F.
Preheating ensures even cooking and optimal results.
Hollow out the centers of the ciabatta rolls slightly and drizzle them with olive oil.
Hollowing the rolls helps hold the filling better.
Spread the bottoms of the rolls with whole grain mustard and sprinkle with half of the cheese.
The mustard adds a tangy flavor that complements the cheese.
Heat olive oil in a skillet over medium-high heat. Sauté the mushrooms for 4 minutes, then add the shallots and garlic and cook for another 3 minutes.
Stir frequently to prevent burning and ensure even cooking.
Add the cooked chicken to the skillet and heat through for 2 minutes. Transfer the mixture to a plate.
Ensure the chicken is evenly heated for the best texture.
In the same skillet, sauté the spinach for 2 minutes until wilted. Season with salt and pepper to taste, then drain any excess liquid.
Draining the spinach prevents the sandwich from becoming soggy.
Assemble the sandwiches by layering the chicken mixture and spinach on the roll bottoms. Top with the remaining cheese and cover with the roll tops.
Press the sandwiches gently to help them hold together.
Wrap each sandwich tightly in foil and bake in the oven for 20 minutes until the cheese is melted.
Wrapping in foil ensures the sandwiches heat evenly and stay moist.
Serve the sandwiches warm and enjoy!
Pair with a side salad or soup for a complete meal.
