1 tablespoon butter
2 slices whole grain bread, very lightly toasted
2 slices Wisconsin Gruyère
2 tablespoons asparagus pesto
Heat a pan over a-little-below-medium heat. Butter one side of each piece of bread.
Place one slice, butter side down, in the pan, top with the cheese, pesto and the remaining slice of bread, butter side up. Grill until the cheese has melted and the bread is golden brown on both sides, about 2-4 minutes per side.
