Heat 1-2 tablespoons of cooking oil in a large skillet or wok over medium-high heat until shimmering.

Add minced garlic and grated ginger to the skillet. Sauté for about 30 seconds until fragrant.

Add thinly sliced beef strips to the skillet. Cook for 3-5 minutes until browned.

Add mixed chopped vegetables and stir-fry for 2-3 minutes until crisp-tender.

Pour in hoisin sauce and mix thoroughly, cooking for another minute.

Add cooked noodles to the skillet and toss for 1-2 minutes to coat with sauce.

Serve hot, garnishing with green onions and sesame seeds if desired.
