On medium heat, melt butter in a small frying pan. Saute onions, peppers and tomatoes for about 2-3 minutes.
In a small bowl, whisk the eggs.
Add the cream, corn, coriander, salt and pepper, and whisk again.
Pour into the frying pan over the veggies.
Allow to cook for about a minute until the eggs set a bit and then begin stirring.
Continue to cook for another 3-5 minutes until eggs are set.
