Sambal oelek (or ulek) is an Indonesian chili paste, which is bright red in color and has a sharp taste. Also popular in neighboring regions such as Malaysia, Singapore and Sri Lanka; it uses very few ingredients, raw red chilis, vinegar and salt. There are loads of brands to choose from, so look for those without additives that have a low carb count. This is the most iconic brand and my personal favorite, which literally contains zero grams of carbs. It lasts forever and is a handy condiment to have in the kitchen.
