Preheat oven to 180 degrees celsius and prepare a baking paper-lined 10” square tin.
Whisk eggs in a large mixing bowl.
Add all ingredients to the mixing bowl, stirring well with a wooden spoon as you go. I recommend leaving the flour to the end and slowly folding it into the mix.
Pour mixture into the lined tin.
Optional: Place 16 cherry tomato halves on top.
Bake for 40-45 minutes, or until golden brown.
Let it cool before removing the baking paper and then cut into 16 squares.
Store in an airtight container in the fridge.
