Method

1. Combine the corn, avocado and tomato in a small bowl. Season with pepper or dried herbs. Set aside. 
2. Whisk the eggs and water together in a small jug. Season with pepper. 
3. Spray a small frying pan with a little olive oil spray and place over medium-high heat. Add half the egg mixture and cook, tilting the pan until mixture covers the base. As omelette sets, lift edge so uncooked egg runs underneath. Cook for 2-3 minutes. 
4. Spoon half the avocado mixture over the omelette. Fold edge over to enclose filling. Turn onto a serving plate. Repeat with remaining egg mixture and avocado mixture. 
5. Serve immediately.
