Leftover Mash Frittata (V)

We had some leftover mashed potatoes and didn't fancy potato cakes, so how to use them up?  The Son disappeared into the kitchen, followed by lots of rattling and clinking noises, and reappeared half an hour later with a plate, a fork, and the instructions to "try this Mum", so I did and it was very tasty!

This is how he made it:

Leftover Mash Frittata

Ingredients

4 medium eggs
1 cup leftover mashed potato (you can also use instant mash instead)
4 green olives mashed
1 cm salami cut into small cubes (optional)
2 green chillies - remove any stalk and finely mash with seeds

Put all ingredients except eggs into a bowl and mix well. Crack eggs into same bowl and mix well.  Put a little olive oil into an omelette or frying pan to prevent sticking. Pour in egg/mash mixture when pan is very hot. Cook on low heat for 20-30 minutes. Serves 2-4.

Vegetarian
If you leave out the salami it is a vegetarian frittata.
