Preparation

Step 1

Using cutter, punch a round from each slice of bread. Spread both sides with butter and top 4 rounds with 2 onion slices each; season with salt and pepper. Close sandwiches.

Heat a large skillet, preferably nonstick, over medium-high and cook sandwiches until golden brown, about 2 minutes per side (onion will soften slightly). Top with parsley and more salt.
