Keep all the ingredients ready. Finely chop onions, capsicum and spinach. In a mixing bowl, add cracked eggs and add milk.

Then beat the eggs until frothy and fluffy with a fork or hand whisk. Then add chopped onions, spinach, capsicum, salt and black pepper powder. Mix everything together.

Now add grated cheese. Give a quick mix. Grease the muffin liners lightly with butter/ghee. Then sprinkle little wheat flour on each liner and turn it upside down. Tap it slightly to get rid of excess flour. If you are using silicon molds, you can skip greasing the muffins liners.

Pour the prepared egg mixture into muffin liners and Bake in the preheated oven for 15-20 minutes (baking time depends on the size of the muffin tray and oven) at 180°C till tooth pick inserted in the center comes out clean. Allow to cool in tray for 5 minutes .
