Hi, As you're really under the weather and if you can afford it, would buying pre-prepared veg help? I'm guessing you are okay with things that take time to cook if it's unattended time.
This takes an hour or two in the oven but it's lovely and filling. Make a simple tomato sauce - onion, garlic, dried herbs, tin of tomatoes, half a tin of water and either a stock cube or a wee splodge of marmite. Peel and slice (pound coin thickness) potatoes and layer the bottom of a lasagne dish with them, to about 2cm thick. Cover with a sliced can of corned beef. Top this with the tomato sauce, then cover with a layer of potato slices. Brush top slices with a tiny bit of oil then shove in an oven for 1 - 1.5 hours, adding a bit more water if it dries out but the spuds are still too firm. I always serve with greens of some form.
Some of the fresh vegetable stir fry mixes are fab. I buy them because there's just the two of us, and that way I get loads of interesting veg in a single bag, but one bag does two meals, so I'm guessing it might be enough for a family. Add either meat (chicken or turkey?) or cashew nuts (our preference) and either a bought stir fry sauce or make your own. I like my homemade one - a splash of soy, a squirt of tomato ketchup, a dollop of honey and some five spice powder, and a splash of white vinegar. I just fiddle with the proportions till it tastes the way I want it that day. When all cooked, serve with noodles. I cook the dry nests, and we like the wholewheat ones but I know the rice noodles are popular.
Fajita type teas, with bowls of different things to choose from so the kids can add their chosen fillings to their wraps.
Small pizzas - I like to use english muffins, cut in half, as the base. Mix tomato ketchup, tinned chopped tomatoes (without too much liquid) and some italian herbs together and spread on the muffin halves. Top with grated cheese and then add whatever your kids prefer. I pre-cook mushrooms so they don't make the pizzas too wet, and obviously meat products are pre-cooked, but otherwise, most stuff goes on uncooked. 15 - 20 mins in the oven.
Frittatta with veg (frozen peas, sweetcorn and green beans work brilliantly in this). Can also be eaten cold next day for lunchboxes.
