Preheat the oven to 350 degrees F.
In a small saucepan, melt the butter until it's browned and nutty, being careful not to burn.
Off the heat, add the worcestershire, onion and garlic powders, herbs, and 1 teaspoon salt and whisk to combine. Set aside.
In a very large bowl, mix the chex cereals, almonds, pretzels, and bagel chips together with a wooden spoon.
Add the browned butter mixture and mix thoroughly to combine.
Spread mixture out on a parchment paper lined baking sheet, taste for salt and add another teaspoon if desired, and pat evenly.
Bake for 30-40 minutes, tossing every 15 minutes to crisp evenly.
Cool and store at room temperature.
