Pre-heat oven to 250 degrees. Put butter in roasting pan in oven to melt.
Mix in Worcestershire sauce and seasonings. Mix nuts into butter thoroughly and bake for 15 minutes. (If any of your nuts are pre-salted, reduce the seasoning salt. You may also wish to reduce seasoning salt if you don't like salty foods. If any of your nuts are pre-roasted, reserve until last 15 minutes of baking.)
Add cereals to nuts and stir well to distribute butter and spices. This first mixing is important to distribute flavors.
Bake for 1 hour more, stirring 3 times.
Allow to cool before storing in airtight container.
