I don't recall the post you're referring to but these salt free blends come to mind–
Mrs. Dash's Original Blend Seasoning, Salt Free (It's a little "peppery".)
Costco Organic No Salt Seasoning
Tony Chachere's Salt Free Creole Seasoning
Penzey's Spices has several salt free blends
Big Ron's Rubs (The web site is difficult to read.)
Pietra's Magic Spice (The web site lists several salt and sugar free blends.)
