Finely dice potatoes, eggs, radishes, and cucumbers. Cut leftover roast chicken, fresh dill, and green onions. Combine all the dry ingredients in a large bowl.
Combine water and kefir (or your choice of ferment) until desired consistency is reached.
Pour kefir mixture over vegetables and season to taste if necessary. Squeeze lemon juice.
Notes
It's best to cook potatoes and eggs in advance and allow to chill overnight in the refrigerator for easier dicing.
Leftover roast chicken meat is best but grass-fed hot dogs and pulled pork also work.
Buttermilk, yogurt, and sour cream can all be swapped for kefir but the water amount will vary. Dilute with water to make the consistency of buttermilk.
To extend life of Okroshka, don't mix in the kefir-water mixture with the dry ingredients until ready to serve.
Dry ingredients can be kept in the refrigerator for up to 4 days in an airtight container.
