are cultured/fermented vegetables (natural probiotics)?
If you have heard of probiotic yoghurt drinks then you may know that the main good thing about these are the beneficial bacteria in them. You can actually grow your own beneficial bacteria using vegetables and this is what cultured vegetables are. Also, since they are grown with vegetables they break down the vegetables, making the nutrients more accessible to your body. Similar to the idea behind sauerkraut and kimchi.
Can be added to salads, used as a side dish, a snack, incorporated into dips, eaten with carbs and especially good with protein. The taste is slightly tangy to strongly tangy (depends on what vegetables you use and how long you leave it in the fridge before you eat it, longer = tangier).
