"Chex mixes" can of course be bought from almost every grocery & mega stores these days, but none of them hold a candle to this tried & true snack from scratch! I adapted my version from a Ladybird Johnson recipe out of a cookbook my husband gave me almost 20 years ago. And no-butter CANNOT be substituted for the margarine. I cook around 1 lb. of bacon to get the grease & drippings needed. Texjoy Steak seasoning is the only one I use. It's available online and limited availability in southern grocery stores.
