Once in a while you want to go back to your food roots--what you ate when you were a kid. Onion Dip made with Lipton Onion's Soup Mix is out (I check the ingredients every time I see it). Try this instead:
2 cups sour cream or light sour cream
2 tsp soy-free beef bouillon powder, or 2 soy-free bouillon cubes
1 Tbsp dried onion flakes
1/2 tsp grain-based coffee substitute, for color (optional)
Crumble the bouillon cubes, if using. Stir all ingredients together. Let sit 5 minutes and stir again.
Soy-free beef bouillon: I used Knorr, but their "cubes" are the same as 2 normal cubes. Also, check the ingredients because sometimes they are soy-free, and sometimes not.
NOTE: For grain-based coffee substitute, I use Postum, but they don't make it anymore. There are other brands, like Pero, but I haven't tried them.
ANOTHER NOTE: as of this posting, Lay's Ruffles and Lay's Light Ruffles potato chips are soy-free.
