Quickest meal for children - Frittata

Sat all day spent at new house and finalising the bathrooms, come home and hungry children. I have almost finished the cooked contents of the big freezer apart from some masala/chilli loaded containers. Found some chorizo/sausage in the freezer and the box of 60 (yes 60!) eggs from Costco and decided on the frittata. Its the quickest meal to cook from scratch in our house. With some salad and nice bread. Macaroni cheese is the next quickest, wish their beloved chapatis /parathas were as quick to do.
Fry some chorizo (essential for flavour), I put in a couple of sausages this time, some frozen mixed veg, olives, sundried tomatoes(again have a huge jar from Costco).
Should add some fried onions/tomatoes too for better flavour, but I rarely do.
After 5 minutes, add 5 beaten eggs flavoured with salt/pepper.
Cook for 5 minutes on highish and then sprinke some grated cheese on the top (yet again bought grated and bagged from Costco) and put under a hot grill for 3-4 minutes.
Sorted.
The middle child hates eggs yet wolfs this down fortunately.
Its like a pastry free quiche which is much easier than making the pastry and baking it first etc.
I vary the contents all the time, sometimes its 4 eggs, sometimes 6, caramelised onions are lovely, lots of possibilities.
Need to do a big food shop today now the children are almost 100% and appetites back.
