To peel shallots, put in a bowl, cover with boiling water and leave for 10 mins.
Drain, peel and trim off roots.
Heat butter and 1 tbsp olive oil in a frying pan over a medium-low heat.
Add shallots and a pinch of salt, cook for 10-15 mins or until softened and lightly browned.
Stir in vinegar, sugar and the leaves from 1 sprig of thyme.
Cook for 2 mins and remove from heat.
Take two 10cm tart tins, preferably without loose bases, and scatter remaining thyme leaves inside.
If using loose-based tins line with greaseproof paper to prevent liquid running out of the bottom.
Split shallots evenly between the two tins and tip in the sticky sauce.
Dust a work surface with flour and roll out the pastry to the thickness of a £1 coin.
Cut out two 12cm diameter rounds and carefully place each on top of the tart tins, tucking in the edges.
Bake for 20-25 mins or until pastry is golden and leave to rest in the tins for 5 mins.
Place the vine tomatoes on a baking tray, drizzle over 1 tbsp olive oil, season with salt and pepper and roast in the oven for 8-10 mins.
Mix the salsa ingredients together, turn out the tarts and serve warm with goat’s cheese, the roasted tomatoes on the vine and a good drizzle of the salsa verde.
