A quick and flavorful sandwich featuring onions and a creamy spread, perfect for a light meal or snack.
Peel the onion and slice it into thin rings.
Use a sharp knife to ensure clean cuts and avoid crushing the onion.
In a small bowl, mix the mayonnaise, mustard, salt, and pepper until well combined.
Adjust the seasoning to your taste by adding more mustard or pepper.
Spread the prepared mixture evenly onto one side of each bread slice.
Ensure the spread covers the entire surface for consistent flavor.
Layer the onion rings onto two of the bread slices, then top with the remaining slices to form sandwiches.
Press the sandwiches gently to help them hold together.
Cut the sandwiches in half and serve immediately.
Serve with a side of fresh salad or chips for a complete meal.
