Soak the lentils for at least 2–3 hours (or overnight), then drain and rinse well.
In a food processor, blend the soaked lentils with eggs, olive oil, and yogurt until smooth and thick.
Transfer the mixture to a bowl. Stir in baking powder, black cumin, chili pepper flakes, chopped parsley, and cheese. Mix until well combined.
Preheat the oven to 180°C (350°F).
Pour the batter into a greased or parchment-lined baking dish or loaf pan.
Smooth the top and bake for 30–35 minutes, or until golden and set in the center.
Let cool slightly before slicing. Serve warm or at room temperature.
