Roast: Place roast on rack in roasting pan; pour in enough water to come 1/4 inch (5 mm) up side of pan. In small bowl, whisk together garlic, mustard, oil, Worcestershire sauce, salt and pepper; brush all over roast.

Roast in 500°F (260°C) oven for 25 minutes. Reduce heat to 275°F (140°C); roast for 50 to 65 minutes or until meat thermometer reads 140°F (60°C) for medium-rare, or 155°F (68°C) for medium. Transfer to cutting board; tent with foil and let cool. Thinly slice against the grain.

Caramelized Onions:
In large skillet, melt butter with oil over medium-low heat; cook onions, salt and pepper, stirring occasionally, until tender and golden, about 45 minutes.

Horseradish Mayonnaise:
In small bowl, whisk mayonnaise with horseradish. (Make-ahead: Refrigerate roast, onions and mayonnaise in separate airtight containers for up to 24 hours.)

Cut baguettes lengthwise in half; brush cut sides with horseradish mayonnaise. Top bottoms with half each of the roast beef, cheese, roasted peppers, caramelized onions and salad greens; sandwich with tops of baguettes. Cut each crosswise into quarters.
