Tip:
To get probiotics into your daily meals there's Kimchi (great with eggs for breakfast), Kombucha tea, plain Yogurt, and Sauerkraut—each giving you different types of bacteria. Add to that Miso, which is commonly used to make miso soup, however the bacteria are likely destroyed in the cooking. Instead add a little miso paste to your salad dressing—it acts as an emulsifier.
Here's a quick dressing recipe from Summer Tomato:
1 Tbsp miso paste, splash of rice vinegar to 1/2 C olive oil, add salt & pepper, fresh chives and some grated ginger to make a nutritious and delicious dressing.
