Heat a little oil in a medium sized frying pan (I use garlic infused olive oil but any will do).
Add your spinach and allow it to wilt down.
Crack your eggs into a jug, season with a little salt and pepper (optional) and beat together. Then pour your eggs into the frying pan.
Sprinkle your chopped ham all over the top of the frittata as well as your chopped chives. Allow it to cook until the edges start to look cooked. It will still likely look quite runny on top.
Sprinkle your grated cheese all over the top and then place in a preheated grill until the top becomes golden (it should only take a few minutes)
Remove from the oven and serve up with some salad. Enjoy!
