Grilled Cheese Sandwich

Method

1. 1Mix softened butter with mayonnaise and garlic powder. Spread this mixture generously on one side of each bread slice — the mayonnaise helps achieve an even, ultra-crispy golden crust.
2. 2Spread Dijon mustard lightly on the unbuttered sides of the bread (this goes inside). Distribute the three cheeses evenly between two sandwiches on the mustard side. Press the sandwiches together, buttered sides facing out.
3. 3Place sandwiches in a cold skillet. Turn heat to medium-low. This is the key — starting cold lets the cheese melt before the bread burns.
4. 4Cook for 4–5 minutes until the bottom is deep golden brown. Press gently with a spatula occasionally. Flip carefully.
5. 5Cook the second side for 3–4 minutes until equally golden. If the cheese isn't fully melted, tent the pan with a lid for 1 minute to trap steam.
6. 6Remove from heat and let rest for 1 minute — the cheese will continue melting and the crust will crisp further. Cut diagonally and serve immediately with tomato soup.
