What you need:
A little olive oil (for frying)
Around 100g (or more) chorizo
1 garlic clove (pressed)
1 green chilli finely sliced (seeds removed)
1 handful of parsley
Salt and pepper
100g (or there abouts) strong grated cheddar
What you do:
Cut the chorizo into rounds and fry in the olive oil until it releases it's own orange juice oils. Add the garlic and fry it for a little bit. Add the chilli for mere moments to suck up some juice.
Break the eggs and whisk them in a bowl and season with the salt and pepper, and add most of the parsley, (keep a little parsley back for a pretty garnish). Tip into the pan with the chorizo and give it a jiggle. Put the grated cheese on top and cook the frittata away until it starts to set. Then move it to the grill and continue cooking. Transfer to a plate and top with the remaining parsley. Eat with bread and butter, maybe.
