Enjoy your bbq. Top tip, precook meat in the oven (except burgers and hot dog sausages) to speed things up.
Think about some super easy meals for you that are suitable from weaning upwards:
Couscous salmon bake
Thaw out aka leave on side) a bag of frozen Mediterranean vegetables,
Make up couscous mixing 200ml boiling water to 150g couscous, add lemon juice (fine to use bottled) and black pepper and a drizzle of olive oil (or normal oil)
Mix veg with couscous and spread into an over dish, lay salmon fillets or side salmon over and loosely cover with foil, put in oven at 200 for 12-15 minutes remove foil squeeze a bit of lemon over and bake a further 2-3 minutes. Can be eaten cold for lunch next day too.
Easy curry
Fry chicken thighs, onions and peppers (use frozen for ease if you want) add half a jar korma paste and a can of coconut milk. Cook 20 minutes. Add chopped coriander at the end.
Cook rice or use packets.
Make a cheat bolognaise, browned mince, frozen onions or soffrito mix, can of chopped tomatoes and jar of sauce.
Chicken bake on pan.
Set oven at 190
Add to roasting pan chicken pieces, new potatoes, chopped butternut squash (no need to peel), couple of peppers roughly chopped, onions chopping roughly, sprinkle with a little oil and Cajun seasoning, bake 40 minutes, drizzle honey and lay tenderstem broccoli on top and return to oven for 8-10 minutes.
These aren't all that cheap but are super easy, kids can help especially using frozen veg, and better than takeaways.
I also would add don't be afraid to accept help from your community, there will be people quite willing to help you out with say a lasagne ready to pop in the oven or a casserole but you need to let them know you would appreciate help. I have a few people locally that I help out when they need it, it's just being neighbourly and letting them know they are not alone.
Take care and make sure you can get some time to yourself, your kids need you to look after yourself. Let us know how things are going in a few weeks.
