Vegan adaptation inspired by the corresponding recipe in Good Lookin' Cookin': A Year of Meals - A Lifetime of Family, Friends, and Food by Dolly Parton and Rachel Parton George. This adaptation uses original wording and plant-based substitutions. The Partons' original published version uses cheddar, Monterey Jack, eggs, whole milk, sour cream, butter, mustard powder, and Velveeta. This version recreates that rich, creamy baked texture with a homemade cashew-miso cheese sauce and no packaged cheese mix.
