Melt the butter in a large measuring cup.

Add soy sauce, Thai fish sauce, lime juice, garlic powder, onion powder, black pepper, and Thai chili paste (if using) to the melted butter.

Let the seasoning mixture sit while arranging the other ingredients in large bowls.

Combine Wheat Chex, Corn Chex, Rice Chex, wasabi peas (if using), mixed nuts, cheese crackers, chow mein noodles, and garlic bagel chips in large bowls.

Pour 1/3 of the seasoning mixture over the cereal mixture in each bowl, stirring well to coat evenly.

Repeat with the remaining seasoning mixture, ensuring all ingredients are well coated.

Spread the mixture evenly across 3 cookie sheets.

Bake in a preheated oven at 275 degrees Fahrenheit (135 degrees Celsius) for 1 hour and 15 minutes, stirring every 15 minutes to ensure even baking and prevent burning.

Remove from oven and let cool completely before serving or storing in an airtight container.
