This Potato, Spring Onion & Feta Frittata is a tasty, light and easy lunch option! If you've not had a frittata before, they are basically a quiche but without the pastry. By using a few tried and tested shortcuts, I've made the process of making this frittata much shorter, but without compromising on flavour. Frittatas are so versatile in that you can add so many different fillings to them. I love this version as it's similar to a Spanish tortilla, but it has the extra addition of spring onion and tasty feta.

Ingredient Tips & Equipment Information
- I use a carton of egg whites, plus a couple of eggs for this recipe. This keeps the calorie and fat content down (as egg yolks are high in calories and saturated fat) and it also saves time cracking loads of eggs! Cartons of egg whites are so handy and they are quite readily available now. The brands I know of are Two Chicks and Happy Eggs. I do add a couple of eggs in the mix too, as it lifts the texture and adds a touch of richness.
- If you would like to use all whole eggs instead, replace the egg whites with 8 whole large eggs.
- I do advise using salt in this recipe, as eggs and potatoes alone can be quite bland and adding salt really lifts the flavour of this dish.
- Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50).
- For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.

What size pan do you need to make this frittata?
I used a 28cm wide frying pan for this recipe. If you use a much smaller pan, the mixture may not fit in it, so you could separate it between two pans. If you use a pan that's only slightly smaller, the mixture may fit but will need longer to cook. You can also use a cast iron skillet to make the frittata.
Can you use whole eggs instead of egg whites?
Yes! If you would like to use whole eggs instead, replace the egg whites with 8 whole large eggs.
How long does the frittata last and can it be frozen?
Once fully cool, you can store the frittata in the fridge for up to 3 days. Wrap it well or put it in an airtight container. You can reheat it in the microwave. You can also freeze the frittata, again wrapped well or in an airtight container, for up to 3 months.

What can you serve with this recipe?
- Bread and butter
- Green salad leaves

- Sweet potato wedges
- Steamed vegetables
- Potato salad

More tips for making the Potato, Spring Onion & Feta Frittata:
- You can swap the spring onion for regular white onion if you prefer
- The frittata will last for 3 days in the fridge and can be eaten cold
- You can bake the frittata in the oven instead of under the grill if you prefer. Check your pan is oven safe, then bake for 15-20 minutes
