Boil a pot of salted water. Cook egg noodles until tender but still firm. Drain and toss with a little oil to keep them from sticking.
Heat 1 tablespoon of oil in a large skillet over medium-high heat. Add sliced steak in a single layer and sear for 2–3 minutes per side until browned. Remove and set aside.
In the same skillet, add a bit more oil if needed. Add shrimp and cook for 2 minutes per side until pink and fully opaque. Remove and set aside with the steak.
Lower heat to medium. Add garlic, ginger, bell peppers, and shredded carrots to the skillet. Sauté for 3–4 minutes until veggies soften slightly but still have a crunch.
Whisk soy sauce, oyster sauce, hoisin sauce, honey, and sesame oil together in a small bowl until smooth.
Add cooked noodles and the sauce to the skillet with the veggies. Toss gently until well-coated and heated through, about 2 minutes.
Return steak and shrimp to the pan. Toss again to combine. Serve hot, garnished with scallions or sesame seeds if desired.
