01 - Lay bread slices on a clean surface and flatten each with a rolling pin until thin and even.
02 - Top each flattened bread slice with a slice of cheese, trimming if necessary to fit the bread.
03 - Firmly roll up each bread slice around the cheese, pressing gently to seal the edges.
04 - Heat unsalted butter in a large nonstick skillet over medium heat until melted.
05 - Arrange roll-ups seam-side down in the skillet. Sauté, turning every 1 to 2 minutes, until all sides are golden brown and crisp, about 6 to 8 minutes in total.
