Wrap leftover sandwiches tightly in foil and refrigerate for up to 2 days. To reheat, warm in a 350°F (175°C) oven for 10–12 minutes or toast in a skillet over low heat until the cheese melts again. Avoid microwaving to preserve the crispy texture. These sandwiches also freeze well — cool completely, wrap individually, and reheat directly from frozen in the oven when ready to enjoy.
With its perfect layers of melted cheese, soft eggs, and flavorful sausage, this Breakfast Grilled Cheese Eggs sandwich is the ultimate handheld breakfast — comforting, satisfying, and irresistibly cheesy.
