Sandwich Ingredients

Method

Preparation Instructions

1

Prepare the Ingredients

Slice the sirloin steak into thin strips. Clean and slice the mushrooms and onion.

2

Cook the Steak

In a skillet over medium-high heat, cook the sirloin steak strips for about 5-7 minutes until browned. Season with salt and pepper to taste.

3

Sauté the Vegetables

In the same skillet, add a little oil if needed and sauté the mushrooms and onions until they are softened and golden brown, about 5 minutes.

4

Prepare the Baguette

Slice the garlic baguette in half lengthwise and toast in the oven until crisp.

5

Assemble the Sandwich

Spread Dijon mustard on the inside of the toasted baguette. Layer the sautéed mushrooms and onions, followed by the cooked steak strips, and top with mozzarella cheese.

6

Melt the Cheese

Place the assembled sandwich back in the oven for a few minutes, until the mozzarella is melted.
