Quick, simple recipes for 18 year old to cook

[Juicecharger]

Hi. I have to leave my 18 year old DS at home alone for the weekend every 2-3 weeks to go a look after my elderly mother. He tends to eat total crap while I'm away i.e. takeaways (fried chicken etc - his favourite food to be honest). I'd love to know of some super easy, and quick recipes that he could make and that are suitable for one person (or will last for a couple of meals). He has ADHD and won't do anything that's too much of a faff. I'd really love him to learn to cook a few things (he generally hates the sort of stuff I cook - stews, curries etc). Any ideas gratefully received.

My asd son has started basic cooking by himself and I won't claim any of these are healthy and some are just snacks but they are quick and easy and he started this by himself.

In sandwich toaster makes lots of cheese toasties, at least one per day.
Hot dogs boiling water in saucepan, adding hot dogs and then buns and ketchup and he washes up the saucepan.
Toast and butter
Hot cross buns and butter
Garlic bread heats in oven
He has also reheated chicken korma in oven but only from takeaway.
Lots of hot chocolate with milk.

He also eats limes and lemons just by themselves so we leave those around.

He also keeps searching for a slow cooker on my Amazon and I am really intrigued as to what he would do with one, he's non verbal so we have no idea and likes all food separated but I am tempted to get one just to see.

Lots of supermarkets do their own version of fried chicken strips/nuggets in the frozen sections that don't take too long to cook, they're not from scratch healthy but better than the take aways.

Pizzas, with a bag of salad and premade coleslaw, fresh pasta takes less time to cook and you can get some stir in pasta sauces, grates cheese and garlic bread is quick.

Get him to come with you at the supermarket and see what he likes the look off and talk through how it would need to be cooked/made and see if he can take that on board.

Yoghurt drinks, muller rice pots, babybels, ham and turkey slices for sandwiches, Swedish meatballs are also quick easy and have some nutritional benefits.

Slow cookers can be used to cook things without it being a stew. Eg in theory you can roast a chicken in it!

My eldest went off to Uni having never cooked, I was happy to do it and knew he'd learn when he had to! His weekly meal plan consists of things like:

Chicken fajitas
Spaghetti carbonara
Curry (jar) & rice
Fresh pasta with spinach, bacon & pesto
Tuna pasta
Burger & chips
Hash browns & eggs
