How to Make Roast Beef Sandwiches with Lettuce and Onions

Step 1: Prepare the Roast Beef

Rinse the roast beef under cold water and pat it dry with paper towels.
Season the meat generously with salt and freshly ground pepper.
Heat 2 tablespoons of vegetable oil in a frying pan over medium-high heat.
Sear the roast beef until golden brown on all sides, about 5-7 minutes total.
Remove from the pan, brush with mustard, and place it on a rack set over a roasting pan.

Step 2: Roast the Beef

Preheat your oven to 140°C (approximately 275°F).
Roast the beef in the preheated oven for about 30 minutes until cooked through.
Once done, remove from the oven and let it rest for 5 minutes before slicing thinly.

Step 3: Prepare Onions and Lettuce

While the beef is roasting, peel and cut the onions into rings.
In the same frying pan used for searing, add more oil if necessary and sweat the onion rings until golden brown, stirring occasionally.
Season with salt and pepper to taste.
Rinse the lettuce leaves under cold water, pat dry, and chop coarsely.

Step 4: Assemble Sandwiches

Toast the bread slices until golden brown.
On four slices of toast, layer thin slices of roast beef evenly.
Season again with salt and pepper if desired.
Top with sautéed onions and chopped lettuce before placing another slice of toast on top.
Cut each sandwich in half diagonally before serving.
