Proper carbonara is nice, quick and easy. Put spaghetti/linguine to boil. Break I egg and one yolk not a bowl, add 4 tbsp of grated Parmesan, pepper and nutmeg, beat and set aside. Fry off pancetta or bacon or bits of sausage, when brown add a bit of vermouth or white wine if you want, and reduce down a bit, add drained cooked pasta to meat, and toss so it is coated in the pan juices. Turn the heat off, and add the egg and cheese mixture to the pan and turn until evenly coated and serve, yum!
Frittata: whisk up a few eggs, grate into the egg, courgette, potato, add peas, or other veg your DC's like, and season. Heat frying pan that will go into oven/grill, add oil and pour in egg, cook on one side, and pop into the grill to finish off the top, serve with bread and butter, and more salad.
Noodles: cook packet of flavoured noodles - I use the Chinese brand ones, add in chopped up leftover meat while it is cookingI.e. chicken, bits from roast, ham etc, add in some green veg like green beans, mange tout, peas etc, and serve.
Couple of wraps/ tortillas warm one in the bottom of a cry frying pan, top with grated cheese, bits of spring onion, a bit of chopped up cooked veg, top with other tortilla and cook through until cheese has melted a bit, flip over, toast other side and then slice into wedges, serve with salad or veg
Dice a couple of potatoes, chop an onion, get a mug each of frozen peas and sweet corn. Wash a couple of mugfuls of basmati rice, set aside. Heat a pan with a couple of tbsp of veg oil, not olive, when warm, add level tsp of cumin seeds, add onion and soften, then add pots and other veg, soften for 5 mins or so, add 2 cloves crushed garlic, inch of grated ginger, and a minced green chilli some salt, 1/2 tsp turmeric, add rice and turn until all mixed. Add 4 mugfuls of cold water, cover and cook until rice is done, and water absorbed, top up with hot water from kettle if you need to, serve with plain yoghurt.
These all go down well with kids and grown ups alike.
