In a large mixing bowl, combine soy sauce, Cajun seasoning, minced garlic, grated ginger, lemon juice, sesame oil, and chili flakes. Add shrimp, crawfish tails, king crab legs, and scallops to the marinade, ensuring all seafood is well-coated. Cover and refrigerate for at least 30 minutes.

Prepare the Noodles

While the seafood is marinating, cook the rice noodles according to package instructions. Drain and rinse under cold water to stop the cooking process. Set aside.

Cooking

Cook the Seafood

In a large skillet or wok, heat a tablespoon of oil over medium-high heat. Add the marinated seafood and cook for about 5-7 minutes, stirring frequently, until shrimp are pink and opaque, and scallops are cooked through.

Add Vegetables

Add the sliced bell peppers and shredded carrots to the skillet. Stir-fry for an additional 3-4 minutes until the vegetables are tender but still crisp.

Combine with Noodles

Add the cooked rice noodles to the skillet and toss everything together, ensuring the noodles are well mixed with the seafood and vegetables. Cook for another 2-3 minutes to heat through.
