Sriracha. It's in my 20% category foods because it's made with sugar...but good luck getting 20% of your daily intake from that stuff LOL.
Frank's is in there too, as well as Tabasco. Balsamic vinegar, it has carbs, but I don't care. Salt, pepper, ms.dash *shrugs*
I like shiitake mushrooms sauteed with onions in butter too.
