Cut beef for grilling into thin slices, then marinate for a few minutes in sweet soy sauce, chopped garlic, lemon juice, and cilantro.
Meanwhile, prepare the filling. To do this, grate a few carrots, chop some fresh mint, then cook your rice noodles as indicated on the package. Rinse with cold water to stop the cooking process.
In a skillet, sauté the beef with the marinade over medium heat for a few minutes.
Place a few lettuce leaves at the bottom of your bowls, add the rice noodles, some grated carrots, beef, and a few roasted peanuts or fried onions.
Sprinkle with sesame seeds, chopped mint, and cilantro.
Add a little nuoc mam sauce on top before serving.
