Hey, great tip. I realized gravy mix was the one thing I forgot when I finally got to the store a while ago. Now I know I will go back and get the pork one to try!
This is one of the only times I can think of when I don't make my own gravy (no drippings). Pan drippings and the browned bits are my favorite part of just about any meat cooking I do.
When challenged one Thanksgiving with having tasteless gravy, even from a real roasted bird, at a relative's house who doesn't cook (thus, empty pantries except for at least 5 little shakers of seasoned salt!) - I managed to scorch some stuff and make it edible.
And oh, I also went to the only open quick-stop convenience store in our part of town and found, of all things, Kitchen Bouquet. I'd never used it before, but it seemed like the thing to get - and it was! Turned wallpaper paste into luscious finger-licking golden turkey gravy.
Kitchen Bouquet is a staple in my kitchen. A splash or two of soy sauce will also help perk up a bland gravy.
