Whether made fresh or leftover, roasted ratatouille-style vegetables not only lend exciting flavor to these Gouda grilled cheese sandwiches but also boost the nutrition factor.
Spread both sides of each bread slice with mayonnaise. Layer 1/2 of the cheese, all of the ratatouille, and remaining cheese on 4 bread slices. Top with remaining bread slices.
Heat an extra-large skillet, grill pan, or griddle over medium heat. Cook sandwiches until golden and cheese melts, 2 to 3 minutes per side.
