In a small bowl whisk together the melted vegan butter, vegan worcester sauce, garlic powder, salt, paprika, and pepper. In a large mixing bowl, toss the rice cereal, corn cereal, pretzels, popcorn, and peanuts together. Pour the sauce over top and toss until the sauce is evenly distributed.
Spread the mixture evenly onto a baking sheet lined with parchment paper and bake in the oven for about 7 minutes! You can cook a bit longer for extra toastiness (I like mine pretty toasty) but be careful not too cook it too long as it burns easily.
