For the cornbread with peppers and feta, first preheat the oven to 220 °C. Wash the peppers, cut them in half, remove the seeds and place them skin side up on a baking tray lined with baking paper. Bake until the bell pepper skin blisters and turns black. Remove and peel off the skin. Puree or dice the peeled peppers.
Cut the feta into cubes. Finely chop the onions. Lightly beat the eggs.
Turn the oven down to 180 °C hot air. Butter a baking dish well.
Slowly heat the milk and fold it into the cornmeal (follow the preparation instructions on the package).
Stir in all the other ingredients. Bake the cornbread with peppers and feta for about 45 minutes.
