This is an adaptation of another snack mix recipe, but I was missing some of the ingredients so I improvised with what I had on hand, and it turned out awesome! I used hot taco seasoning mix to spice it up some.
In a large roasting pan, combine all ingredients except butter and seasoning mix.
Mix melted butter and seasoning mix in a small bowl until well blended. Pour over cereal mixture; toss to coat.
Bake 25-35 minutes, stirring two or three times, until lightly browned. Sprinkle with parmesean cheese. Spread on paper towels or waxed paper until cooled, about 15 minutes. Store in tightly sealed containers. Makes about 12 cups.
