Sandwich with Roast Beef and Caramelized Onions

I will guide you through the steps to create a succulent sandwich with roast beef and caramelized onions. Remember that caramelized onions may take some time and patience, but the result will definitely be tasty.

Ingredients

• 4 slices of bread, preferably rustic or rye
• 200 g of thinly sliced roast beef
• 2 large onions
• 2 tablespoons of brown sugar
• 2 tablespoons of balsamic vinegar
• 1 tablespoon of butter
• Salt, to taste
• Black pepper, to taste
• Mustard or mayonnaise, as desired
• Arugula or mixed salad, for garnish

Preparation

1. Start by preparing the caramelized onions. Cut the onions into thin slices.
2. Melt the butter in a pan over medium heat. Add the onions and cook until they start to soften, stirring occasionally.
3. Once the onions are soft, add the brown sugar and balsamic vinegar. Lower the heat and continue to cook slowly, stirring often, until the onions turn a nice golden brown and caramelized. This process could take about 30 minutes. Adjust salt and pepper to taste.
4. Toast the slices of bread until they are crispy and golden.
5. Spread a thin layer of mustard or mayonnaise on two slices of bread, according to your preferences.
6. Distribute the roast beef on the slices with mustard or mayonnaise.
7. Add a generous spoonful of caramelized onions on top of the roast beef.
8. Add some arugula or salad for a fresh and crunchy touch.
9. Cover with the other two slices of bread, pressing down slightly.
