Fried Eggs with Rosemary Sauteed Potatoes

Serves 2

Ingredients

• 425g new potatoes
• 1 tbsp butter
• a few springs of rosemary leaves, chopped
• 1 onion, chopped
• 2 eggs
• 1 tbsp oil
• 150-200g of spinach

1. Cut the potatoes into cubes and, in a large frying pan, fry them in butter for 15 mins until golden and cooked through.
2. Five minutes in, throw in the onions  
3. Tip in chopped rosemary leaves and fry for a few minutes until softened.
4. Push the potatoes and onions to the side of the pan and add a further 1tbsp oil or butter. Break in the eggs and fry to your taste.
5. Serve the potatoes piled on two plates and top each serving with a fried egg and spinach on the side, or fry only one egg and save half of the potatoes for leftovers

This was pretty delicious and a well balanced meal. I don't think the spinach went too well with it but that might have been the brand. When I used the leftovers, I fried the spinach leaves in a bit of olive oil and that went over better.
Conceptually, all this took was some chopping and frying. There was nothing too complicated about it and there was enough for two servings.
