Preheat the oven to 180c.
Line your pastry tin with the pastry and blind bake for 20 minutes.
Meanwhile, melt the butter in a frying pan and add the onions, some salt, lots of pepper, balsamic vinegar and the sugar. Let them sweat down over a low heat for half an hour or until collapsed, golden and a bit like marmalade. Leave to cool.
Whilst the onions are sweating down, place the cream cheese, thyme, nutritional yeast and ¼ teaspoon salt in a bowl and mix until you have a spreadable mixture. Taste for seasoning and adjust as necessary.
Spread the cooled onion mixture over the pastry case then gently spread the cream cheese over the top of this then top with the tomatoes, still on the vine. Grind over some more black pepper, a pinch of salt and a little olive oil.
Turn the oven up to 200c.
Bake for 30 minutes or until the tomatoes start to pop but not collapse.
Leave to cool for about 10 minutes before unmoulding.
Please note that where the recipe asks for milk, butter or yogurt, this refers to any plant-based version that you prefer.
