Recipe: frittata

Ingredients to make one frittata that does between two and four portions, depending on how greedy hungry you are
4 eggs
a dollop of quark
pinch of mustard
a squidge of garlic puree (or a shake of garlic granules)
60g finely grated cheese
salt and pepper
spray oil
a selection of vegetables which, I think, MUST include some potato (pre cooked or leftover).  For the one in the photo I used onion, pepper, mushroom and potato
Some bits of cooked meat, if you want - not essential.  I used some ham.

It also helps to have a small to medium sized frying pan that can go under the grill or in the oven

Method.
If you're using the oven, preheat to about 180C

Crack the eggs into a bowl, add the quark, mustard powder, garlic puree, a bit of salt and some pepper and about 20g of the cheese and whisk well, using a hand held electric whisk, if possible.  Cover and set aside.
Peel and slice a small onion, de-seed and chop half a red, yellow or orange pepper and slice three or four mushrooms.
Spray the pan with fry light or equivalent, heat, add the onion, stir and saute slowly until the onion is softening, stirring now and again.  Then add the pepper and mushroom and continue cooking for about five minutes.
Finally, add any meat and the cooked potato, sliced and let them all heat up.
Pour over the egg mixture and sprinkle over the rest of the grated cheese.
To cook, either . . .
pop the pan into the oven for about twenty minutes or so until cooked through
or . . .
keep the pan on the hob until the base is cooked and browning (carefully lift it up to take a peep now and again) and then, when it's almost done, pop the pan under the grill to cook on top and brown the cheese.

Serve either hot or cold, cut into wedge-slices.

Really, you can use whatever you have in this.  Peas, sweetcorn, asparagus, roasted veg, tomatoes, chickpeas - whatever you have.  Ditto with seasonings - some herbs would work nicely. 
Just make sure everything is cooked before you pour over the egg.

I suppose the quark isn't essential but I think it adds flavour and a certain 'creaminess' to the finished frittata.  It's SW free and adds a bit of protein.

SW info:  Just two healthy extra As for the cheese.  However, not suitable for an SP day due to the potato (which I do think is essential).
