Frittatas are a quick and easy alternative to quiche, and healthier because they contain less cream and don't need pastry. I use a heavy cast iron pan, which always produces great results and looks great on the table.
If you have any leftover roasties, these make a delicious addition to the frittata! Simply cut into small cubes and add along with the chorizo.
Use jarred roasted red peppers, or use peppers that you've roasted yourself. In a pinch, use fresh red peppers, but cook them longer on the hob till they soften.
The cheese lends loads of flavour to the frittata; you can get creative and add your favourite cheese, or a mixture of cheeses. A sprinkling of grated Parmesan or Pecorino Romano is a great addition and lends a nice saltiness.
