Best of all....you don't have to be a top baker or an experienced cook to make it: it uses shop-bought ready rolled pasty and only five simple ingredients.
So what are you waiting for? Try and get top quality tomatoes with plenty of flavour for this one - John recommends mixed heritage tomatoes which add colour as well (as seen in the pic above).
'The vibrant colour of mixed heritage tomatoes is awesome,' John writes. 'There is a whole palette to choose from.
'I particularly love the green tigers, with their verdant skin and dark green stripes and those tiny little yellow ones with a zingy, sharp flavour.
'This tart is gorgeous served slightly warm, but I personally prefer it once it has cooled completely.
'The flavours just seem to have found one another by the time it has come to room temperature.'
- 320g packet ready rolled puff pastry
- 100g soft goat's cheese
- 400g mixed-colour heritage tomatoes
- 70g pitted black olives
- A few sprigs of thyme
- Sea salt flakes
- Coarse black pepper
- Extra virgin olive oil
Method1 Preheat the oven to 200°C/180°C fan/gas mark 6.
2 Unroll the pastry onto a baking sheet, and with a sharp knife score a 1cm margin around the edge of the pastry – don't cut all the way through, but use enough pressure so that the score line is visible.
3 Crumble the goat's cheese over the pastry, keeping it within the margin. Slice the tomatoes fairly finely – if you don't have a really sharp chef's knife, a serrated knife is always a good option.
4 Arrange the tomato slices, as higgledy-piggledy as possible, on top of the goat's cheese and sprinkle over a pinch of salt and pepper. Roughly chop the olives and scatter them over the top of the tomatoes along with the thyme.
5 Bake the tart in the oven for 25–35 minutes, or until the pastry has puffed up around the tomatoes and is a light golden brown. Drizzle over a little extra virgin olive oil and serve.

Chef's tip: 'Thyme is a personal favourite, but sprigs of fresh oregano are just as beautiful. Tarragon or rosemary are very interesting, but not to everyone's taste; the choice is yours.'
