A spicy grilled cheese sandwich is a fiery twist on the classic comfort food. It typically features melty cheeses like pepper jack or cheddar, combined with spicy ingredients such as jalapeños, chili flakes, or hot sauce. Some variations include roasted peppers, spicy mayo, or even chipotle-infused cheese for an extra kick. The bread is buttered and grilled to golden perfection, creating a crispy, crunchy exterior that contrasts beautifully with the gooey, spicy filling.
