Oatmeal and Kefir Bake with Carrots, Apples, and Walnuts

Combine the oatmeal and kefir in a bowl and leave it for 5 minutes.
Add the eggs and honey (or syrup) to the oatmeal mixture and mix well.
Grate the carrots on a fine grater and add them to the mixture.
Peel, core, and grate the apples, then add them to the mixture as well.
Pour the mixture into a baking dish and bake at 180°C (350°F) for 40-45 minutes.
Optionally, add walnuts for extra flavor and texture.
