If they like the chicken wings then they can do them with salt, pepper and a bit of paprika, use spray oil on them first (or proper oil but it can be greasy) or flour and herbs and then fry or BBQ.
If they want a dip with them then a raita (finely chopped cucumber and mint sauce in Greek style yoghurt) or a garlic dip with a 50/50 Greek style yoghurt with a crushed bulb of garlic (or you could use the stuff in a tube).
If they like Thai / Indonesian then a really easy broth is boiling water, with a frozen cube of ginger and a frozen cube or garlic. Or you can use a couple of garlic cloves and about 1inch of fresh ginger (peeled).
Once that is in the pan you can add what you want, meat, bok choy, spring onion, chili (fresh fried or powdered) whatever is in the cupboard / back of the fridge again add instant noodles.
You said they liked mince, so meatballs of various types might work. Obviously shepherd's / cottage pies - probably one to make for the freezer.
Home made burgers, meatloaf, kofta kebabs, chilli, burritos.
I live on my own so I often plan to have left overs so if I make a chili the following day I will take left over chili, left over rice and often some grated cheese, put in the middle of a flout tortilla and wrap all four sides in so you have a square 'parcel', put on a baking tray in a roasting pan with the 'open' bit underneath and bake for 20 - 30 mins. They can be eaten as soon as they come out of the oven but if you let them go cold they sort of seal themselves nd you can take them in a packed lunch.
Another two stage meal I do is chicken in the slow cooker (so not yet until they get a sc, but it would work in a pan) is chopped chicken breast in the slow cooker with sliced mushrooms and I sometimes put leeks in as well, add a tin of condensed mushroom soup (which has enough salt and seasoning in it that you don't need to add any) and a pot of crème fraiche. Just leave it all day.
Serve with potatoes or eat with crusty bread.
The next day put the left overs in a pie tin or foil container and top with ready rolled puff pastry - I tend to freeze this pie.
Will they eat veg soup? I make a soup using the bits of veg you normally throw away so cauliflower and broccoli stems, cauliflower leaves and whatever is in the back of the fridge. I put them in the slow cooker with boiling water or stock and then blend with a stick blender.
