Boil dry rice noodles in water for 3 to 4 minutes, drain, rinse thoroughly under cold water, and divide among 4 bowls.

Mix fish sauce, lime juice, sugar, sliced chili pepper, remaining garlic, remaining shallot, and 4 tablespoons of warm water to create Nuoc Cham dressing.

Heat canola oil in a wok or skillet over high heat at 200°C (390°F) and stir-fry marinated beef sirloin rapidly for 3 to 4 minutes until browned.

Top noodles with shredded lettuce, cucumber, carrot, bean sprouts, fresh mint, cilantro, and hot stir-fried beef, then garnish with crushed peanuts and serve with dressing.
