I do use  a few packaged dry mixes – even though the’re loaded with sodium – some of them I can’t resist:
Hidden Valley Ranch Buttermilk – it’s great in Fiesta Soup and shrimp dip
Any Taco or Fajita – Also good in Fiesta Soup, tacos & fajitas
Beef Stew Seasoning – it makes it better
And my latest favorite – Zatarain’s Creole Red Gravy – this stuff is fantastic!  I’ve used it on Stuffed Cabbage, Pork Chops and Chicken – now the store I was buying it from doesn’t have it and if I buy it online it’s  $1.29 a package but shipping is $8.95 for 6 pkgs.  It’s some good stuff, though.
