Recipe Information
Ingredients
- 1 medium-sized Red onion
- 4 slices Rustic bread
- 2 tablespoons Mayonnaise
- 1 teaspoon Dijon mustard
- 2 tablespoons Butter
- 0.5 teaspoon Salt
- 0.25 teaspoon Black pepper
- 1 tablespoon (chopped) Fresh parsley
- 2 slices (optional) Cheddar cheese
Instructions
Peel the red onion and slice it into thin, even rounds, approximately 1/8 inch thick.
Toast the slices of rustic bread until golden and crisp.
While the bread is toasting, prepare the spread by mixing mayonnaise, Dijon mustard, salt, and black pepper in a small bowl.
Heat a small skillet over medium heat and melt the butter. Sauté the onion slices in the butter for 2-3 minutes until softened but still slightly crisp. Remove from heat.
Spread the mayonnaise-Dijon mixture evenly over one side of each toasted bread slice.
If using cheese, layer a slice of cheddar cheese on two pieces of the bread. Top the cheese with the sautéed onions, spreading them out evenly.
Sprinkle the chopped parsley over the onions for added freshness and flavor.
Close each sandwich by placing the remaining slices of bread on top, spread-side facing the onions.
Cut the sandwiches in half, if desired, and serve warm or at room temperature.
