Instructions

Preheat Oven: Preheat your oven to 400°F (200°C) to prepare for roasting the vegetables.
Prepare Vegetables: Clean and slice the mushrooms and onions. In a bowl, toss them with olive oil, half the salt and pepper, garlic powder if using, and chopped thyme or rosemary if desired. Spread them evenly on a baking sheet.
Roast Vegetables: Place the baking sheet in the oven and roast for about 20 minutes until mushrooms are golden and onions caramelized, stirring halfway through to ensure even cooking.
Assemble Sandwich: Butter one side of each bread slice. On the unbuttered side, layer a generous amount of Gouda cheese, followed by the roasted mushrooms and onions, then another layer of Gouda cheese. Top with the second slice of bread, buttered side facing out.
Grill Sandwich: Heat a skillet over medium heat. Place the sandwich in the skillet and cook for 4-5 minutes per side, or until the bread is golden brown and cheese melted. Covering the skillet helps melt the cheese evenly.
Serve: Remove the sandwich from the skillet and let it cool briefly. Slice in half and serve warm, optionally paired with tomato soup or a simple salad.

Notes

You can substitute vegan cheese and butter to make this vegan-friendly.
Use gluten-free bread to accommodate gluten-free diets.
Adding fresh herbs like thyme or rosemary enhances the flavor but is optional.
Covering the skillet while grilling helps the cheese melt better.
Adjust seasoning to taste, especially salt and pepper for the roasted vegetables.
