Preheat your oven broiler to high.
Slice the low-carb sandwich rolls in half horizontally. Place them cut side up on a baking sheet.
Place one slice of Swiss cheese on each bottom half of the rolls.
Broil the rolls for 2-3 minutes until the cheese melts and the tops of the rolls are toasted. Keep an eye on them to prevent burning.
While the rolls are toasting, wash and pat dry the lettuce leaves.
Slice the tomato thinly and the red onion into rings.
In a small bowl, mix the horseradish sauce and mayonnaise together thoroughly.
Remove the rolls from the oven and let them cool for a minute.
Spread the horseradish mayonnaise mixture evenly over the cut sides of each roll.
On the bottom half, layer two lettuce leaves, tomato slices, a few onion rings, and half of the roast beef.
Season the sandwich fillings with a pinch of salt and black pepper.
Place the top half of the roll on the sandwich, gently pressing it down.
Repeat the assembly for the second sandwich.
Serve immediately and enjoy your low carb classic roast beef sandwich.
