Slice the baguette or sandwich rolls in half horizontally. Lightly brush the cut sides with olive oil.
Toast the bread halves in a skillet or under a broiler for 2-3 minutes, or until they are golden and slightly crisp. Set aside.
Wash and dry the lettuce leaves, and set them aside.
Slice the tomato into thin circles and the red onion into very thin rings. Pat them dry with a paper towel to remove excess moisture.
In a small bowl, mix together the mayonnaise, prepared horseradish, Dijon mustard, salt, and black pepper to create a creamy sauce.
Spread an even amount of the sauce onto the bottom halves of each toasted baguette or roll.
Layer the lettuce leaves on top of the sauce, followed by the sliced tomatoes and red onion rings.
Evenly divide the roast beef slices between the two sandwiches, placing them on top of the vegetables.
Place the top half of the bread on each sandwich and press down gently to secure the layers.
Cut the sandwiches in half for easier handling, if desired, and serve immediately.
