Add apple cider vinegar, spices, and baking soda. Beat the batter until the baking soda has dissolved.
Grease the baking dish with oil, pour in the batter, and sprinkle with cumin and coriander seeds. Bake the bread for 40 minutes. Then reduce the oven temperature to 170°C (338°F). Bake for 20 minutes. Check with a wooden skewer to see if the bread is ready.
The baked meatloaf can be cooled on a wire rack.
Cut into slices once the meatloaf has cooled completely.
