if you have a slow cooker it's worth investigating Dump Bags.
The gist of it is you spend a couple of hours prepping your veg, portioning up the meat, bagging it all up so it is ready to defrost, tip into the slow cooker with tinned toms/stock
so I did a sweep on the reduced counter the other week, picked up some diced chicken, some chicken breasts and some casserole beef
I don't like SC meals where the stuff is just hurled in un cooked, so I chopped and sweated a huge pile of onions and celery and also some red onions and celery, and let that cool, I usually also brown the meat but I didn't want to risk that and tbh that certainly did not seem to make a difference, whereas I do think the onions and celery are never right unless they have been sweated off properly.
I ended up with
Spanish chicken....sliced breast, good dollop of onion mix, left over chorizo, plenty of seasoning, some crushed garlic ...put into bag, and when it goes into the SC you add passata and tinned white beans and a splash of wine
Country Chicken...diced chicken, sliced leeks, bacon, seasoning, onion mix, BAG and freeze. Add tinned toms and white wine as it goes into the SC
I also did Chicken Satay, a beefy chilli curry effort, a beef and mushroom thing....that ended up as a pie filling, and Sweet ginger beef....that's loosely based on HFW sweet/sour beef.
