Use thick, sturdy bread like brioche or challah and day-old bread for best results. Soften cream cheese before spreading. Be careful not to soak the sandwiches too long to prevent sogginess. Cook on medium heat to avoid burning. For variations, try different fruits, fillings, or vegan substitutes. Leftovers can be stored in the fridge for up to 2 days or frozen for up to 1 month.
