Begin by cooking the egg noodles according to package instructions. Once cooked, drain and rinse under cold water to stop the cooking process. Set aside.
In a bowl, combine the soy sauce, oyster sauce, hoisin sauce, brown sugar, and sesame oil. This will be your sticky sauce.
In a large skillet or wok, heat a drizzle of oil over medium-high heat. Add the minced garlic and grated ginger, sautéing until fragrant for about 30 seconds.
Toss in the sliced beef and stir-fry for 2-3 minutes until browned but not fully cooked through.
Add the sliced red bell pepper and sugar snap peas to the skillet. Stir-fry for another 2 minutes until the vegetables are tender-crisp.
Pour the sticky sauce over the beef and veggies, stirring to combine thoroughly. Let it simmer for about 2 minutes, allowing the sauce to thicken and coat the ingredients.
Finally, add the cooked noodles into the skillet, tossing them with the beef and sauce until evenly mixed and heated through.
Remove from heat and serve hot, garnishing each portion with chopped green onions and a sprinkle of sesame seeds for added flavor and crunch.
