I think you need to take in to consideration what utensils / appliances and storage are available. It might be one cupboard and one fridge shelf.
For cooking a good knife is IMHO essential, but keep in the student's room not the kitchen.
Argos do a small slow cooker I think others do as well but here is a recipe that will feed one person for 2 days, or two people for one.
Pork ribs - I prefer the ones that are joined together
1 jar passatta
1 tin of beans - I like butter beans but any will do
Salt and pepper and any dried herbs /spices - I like smoked paprika.
Switch on the slow cooker
Put the ribs in, if you have got the ones joined together then they will fit sort of lining the sc
Drain the tin of beans and add to the slow cooker
Add in the passatta
Go to lectures / library / pub for a few hours
The bones will actually come out of the ribs so remove them before serving, I find it easiest to do this with chop sticks.
Once it looks like pulled pork in a tomato sauce it is ready to eat.
I like to have this with crusty bread
Pasta with cream cheese.
You can do this just with pasta and the cheese but you can add in mushrooms, bacon, chicken, veg. I'll do a mushroom recipe here
Philadelphia style cheese
Pasta
butter / oil (you don't need this if you are just using the cheese)
salt and pepper
Put the pasta in water and heat
Slice the mushrooms
when the pasta is about 5 mis from cooked add the oil / butter tot eh pan and then add the mushrooms with seasoning
Keep the mushrooms moving so they don't stick
Once the mushrooms are cooked add a dollop of cream cheese, about half the packet will be plenty
Add a couple of spoonfuls of the water the pasta is cooking in
keep stirring the cream cheese and mushroom mixture, drain the pasta and then add it to the mushroom mix.
To save washing up you can eat from the pan.
One bit of advice is to use tins / cans as substitutes for fresh so if you have a recipe for fishcakes then try it with tinned fish rather than fresh.
Really easy cottage pie
1 tin of minced beef and onion
1 packet of instant mashed potato
Optional frozen or tinned or even fresh veg
You do need a casserole dish.
Boil the kettle
Open the tin(s), pour the mince in to the dish
Make the mash
Dollop mash on top of the mince and put in the oven for 20 - 30 mins
