I'm pretty sure that my friends and I ate a lot of toast (took our own toaster), toasties (same), tinned soup. If he's allowed to take a toaster I would strongly recommend it.
I got pretty jazzy with microwave cooking because my halls had no food included (they had a canteen where you could buy it, but nothing included) and no hob. So here's the microwave cooking document my friends and I made before we left - long post incoming! Haven't looked at this since I left uni!
Snacks
‘College pizza’ - toast a pitta bread, melt cheese in the microwave, spread tomato puree on the pitta, add melted cheese on top and add whatever toppings you want.
Nachos - tortilla chips, cheese, refried beans if you so desire. Microwave til cheese bubbling, serve with salsa and soured cream/creme fraiche.
Basics
Potatoes (10mins, covered with boiled water, pierced clingfilm over the bowl)
Pasta (time it says on the packet, covered with boiled water)
Baked potatoes (7-8 mins on full power)
Polenta (1:4 ratio cornmeal to water/stock/milk, boil liquid, add cornmeal, whisking as you add. Microwave til done - 5-10 mins? Stirring approx every minute. I think it’s good left to set, and then baked, but I know not everyone has an oven - I thought cold and set it was still pretty tasty.)
Onions seem to fry just fine in a pyrex bowl (3mins, stir then another 2-4mins)
Poached egg: fill mug half with water, break an egg into it, put it into microwave on lowest setting for about a minute (but keep checking so it doesn’t explode)

Meat/Fish
Bacon (~3 mins, over rim of cup sitting in a bowl)
Fish (poaches fine, just cook til opaque. Can poach in a little bit of wine for tasty-ness)(can also microwave with roule on top for tastyness - and then eat w/ potatoes, or flake into pasta)
Sauces
Cheese sauce (2oz cornflour/flour, 1/2tsp mustard powder, mix gradually with 1pt milk, heat til boiled stirring ~ every 1 minute, add 5oz cheese)
Carbonara (Bacon first, then pasta, then beat with eggs and cheese)
Tomato and ricotta sauce (Boil passata in microwave, stir in ricotta/soured cream/creme fraiche, plus a pinch of sugar and some oregano, pepper etc.)
Tuna-tomato sauce (Chop onions, heat in oil on high for 1-2mins, add tinned tomatoes, squeeze of tomato puree, tin of tuna, oregano, heat through)
Generic tomato sauce (Fry onions 3mins, add diced carrots for another 2-3mins, tin tomatoes, garlic/garlic puree, oregano, thyme, basil - can add peppers etc if you want. I like to do it as a 5 a day tomato sauce sometimes - onions 2mins, add diced courgette, another 2-3 mins, add diced peppers and grated carrot - another 2-3mins, Andy then add tomatoes, herbs etc.)
Pudding
Microwave pudding (2oz butter/marg, 2oz sugar, 2 oz SR flour, 1 egg, pinch baking powder poss. Mix. Put 1+ tbsp Golden Syrup/Jam/Alternative in base of pudding basin, pour mixture on top. Microwave for 3.5mins, covered with pierced clingfilm. Can substitute 1tbsp flour for 1tbsp cocoa. Can also add dried fruit etc.)
Crispy cakes (Melt 4oz butter, with 4oz icing sugar and 4 generous tbsp golden syrup, add 6tbsp cocoa and boil a bit, mix with 6oz cornflakes/rice crispies and put in a tin (can line with cling film for easy removal and reduced washing up).)
