If you’ve the budget - I have a Ninja Speedi which has changed my life.
I tend to use frozen vegetables on sauté mode then add in mince, protein etc for a chilli and put it on steam air fry.
You can do one pot meals - things like tuna or bolognese pasta bake, macaroni cheese, rice based dishes.
Roasts are easy…you can bung a chicken and all the potatoes/veg in.
I often do jacket potatoes in it and they come out cafe style..then a bagged salad, grated cheese, beans, chilli from the freezer, tuna deli filler etc.
You can do a full English in it.
My emergency go to is cook some M&S or Aldi Tempura Chicken in the top, then remove once done, switch to sauté mode, bung some stir fry oil, chopped spring onion, a couple of eggs, soy sauce and a packet of ready cooked rice (I use Veetee but Uncle Bens etc fine), Serve with a packet of sweet and sour sauce and you have Chinese fakeaway. 15 mins from start to finish.
Some times I do fish, chips and a tin of peas…low fat options when possible,
Clean up is sooooooooo easy. You can also get disposable liners or silicone trays.
I know not a recipe, but definitely a game changer if you want quick meals, largely from scratch.
