Roasted vegetable lasagne with goats' cheese

It's harvest time - or at least, so the Fortnum and Mason shop window tells me (I was walking past, not doing my shopping there, I hasten to add). Living in a city, you can feel disconnected from these landmarks in the food year, these rural rituals. But even I can spot all the cheap courgettes in the market, and if you have an allotment or vegetable garden, you're probably rushing to use them before they turn into marrows.

A roasted vegetable lasagne feels like a fittingly celebratory dish, stuffed full with shiny plump vegetables - not just courgettes but aubergines, onions, peppers and tomatoes. I've been making it for years. Actually, it was probably one of the first proper dishes I made without a recipe, and I've loved it ever since.

Portuguese wine

I don't usually write about wine, but a few days ago I went to a wine tasting at a slightly unusual venue - a library. I haven't been to many Lambeth Heritage Festival events, but they cover an impressive range of topics. (There's one coming up very soon, on the evening of September 23, on London in the First World War with Professor Jerry White, an award-winning social historian).

I have to admit I previously knew very little about Portuguese wine, but this event certainly opened my eyes.

Two late summer salads

Picnic opportunities are fast running out, but I am planning to squeeze in one or two more. This weekend I enjoyed two easy dishes which celebrate vegetables, using strong flavourings to add punch to main ingredients which might seem rather pedestrian - cucumber and carrots. The winner to my mind was spiced carrots teamed with feta cheese, the spices helping to bring out the sweetness which was balanced by the salty feta. But I will certainly be making the garlicky smashed cucumber again too.

Personally, if I had these two dishes on a picnic I wouldn't need much else, though I might be tempted by the idea of some fresh bread and some home-made hummus. But it rather depends how lavish your idea of a picnic is. And if you're not picnicking, never fear - either or both of these will work well indoors, perhaps as a light lunch or side dish.

The ten best things to do with blackberries

It's been a great year for blackberries. They seem to be everywhere - not just on country lanes and in fields but in London parks and alongside railway lines, anywhere in fact, urban or rural, where they can find a foothold.

A few days spent camping in Wales recently gave me the opportunity for lots of blackberry-picking - although coastal walks became rather slow and protracted when I kept getting distracted by new patches of shiny, juicy fruit.

Potato salad with attitude

As I write, there's a disconcerting chill in the air. This evening I've pulled on a jumper for the first time in a while. But I've not quite done with summer eating yet.

I hope that the sun will find its way out again soon. Either way, here's a potato salad that will add some excitement to even the dullest day. I like potato salad but all too often they can be bland, mushy and greasy. This one is light, low in fat and full of lively flavours.

Griddled courgettes with goats' cheese, couscous and beans

I confess to a slight love affair with griddled courgettes at the moment. Courgettes seem to be around in abundance, and griddling them in long strips gives them both sweetness and interesting charred notes.

With the help of some frozen vegetables, this easy dish took me less than 20 minutes to put together - ideal for a quick dinner after work.

The best chocolate mousse in the world

Usually I try to post recipes that are vegetable-centric, and healthy where possible. But we all need indulgences sometimes. On this occasion we were having people round to dinner and a dessert was required. In fact, a dairy-free dessert was required. But this dish is so rich and indulgent that it wouldn't strike you as free-from anything.

Chocolate mousse might sound complicated to make, but as long as you can separate eggs and have an electric whisk, it's not at all. The only slightly tricky part is mixing in the egg whites without knocking all the air out of them, but with patience and a gentle hand you should get there in the end. (It strikes me that this could equally be advice for bringing up children.)
