• Preheat your oven to 400 degrees
• Line a sheet pan with foil and lay out your bacon strips. Bake in the oven until crispy - about 20 minutes.
• While your bacon is cooking, add olive oil to a preheated pan then add in your onion and red pepper. Once your onions start to caramelize, add the fresh spinach and a pinch of kosher salt. Saute until onions are slightly caramelized and your spinach is wilted. Remove from the pan nd set aside.
• While your vegetables are cooking, make the compound butter. Combine the butter, parsley, parmesan cheese, and garlic powder. Mix until incorporated. Set aside.

Assembly

• Butter one side of each piece of bread with the compound butter. In your preheated pan, lay one slice for each sandwich butter side down.
• Add pepper jack cheese, sautéed vegetables, bacon, and mozzarella cheese then top with another slice of buttered bread, butter side up. Cover with a lid and let the cheese melt and the bread crisp. Flip the sandwich over and if your cheese has melted properly you can leave the lid off.
• Once the sandwich is cooked, let cool on a wire rack so you won't have soggy bread.
• Enjoy!
