Mediterranean vegetables, halloumi and couscous

I made this a while ago when your Gran and Grandpa were here, but then I gave Gran the vegetarian cookery book I filched the recipe from, so I've no idea if this is the same thing or not.

Makes enough for four:

an onion, sliced
a clove of garlic, chopped
two peppers (red/yellow/green/orange - doesn't really matter), sliced into chunks
a courgette, sliced
some mushrooms, quartered

(you could also add aubergine, or whatever else is lying around)

a tin of tomatoes, and a squirt of tomato puree
herbs - some thyme, oregano, mediterranean herbs - whatever you've got really

couscous (about 1/4 of a 500g bag - depends how greedy the people are that you're cooking for, I suppose)
a block of Greek halloumi cheese (couple of hundred grams or so...)

Fry the onions and garlic in some olive oil until they are translucent. Add the peppers, cook for a couple of minutes until they soften, and then bung in the courgette and mushrooms (you might have to add a little more olive oil at this point. Cook for a couple more minutes, then add the tin of tomatoes, tomato puree, a screw of black pepper and a teaspoon of herbs. Simmer for a while - it's probably edible after 20-30 minutes, but it's better when you leave it for an hour.

The halloumi's really nice if you slice it, and put it into a greased griddle pan (brush it with olive oil) on a high heat - you should get some nice stripes if you fry them for 30s-1 minute on each side.

For the couscous: melt a knob of butter in a saucepan, and add the couscous grains, coating thoroughly. Add boiling water - enough to cover the couscous by about a centimetre. Let it bubble away for a couple of minutes until the water has been absorbed, then stir with a fork, to break the grains up. Check how hard it is - you may have to add some more water and give it a little longer.

To serve: take four bowls, dollop some couscous in each. Slosh the mediterranean vegetables on the top, and then place three or four slices of halloumi on each portion.

Me, your gran and your grandpa had this for tea, but you said you didn't like the squeaky halloumi cheese, so yours came with a few slices of chorizo instead.
