Before I serve the potatoes, I crush them slightly with the back of a fork and they almost become fluffy gnocchi, ready to absorb the flavours of the ingredients they are cooked with.
Cook the potatoes in a pan of salted boiling waterfor about 10 minutes, until cooked through. Drain.
Pan-fry the sliced garlic in a splash of olive oil over a medium heat for a few minutes until it startsto brown, then add the chilli flakes, passata and cooked potatoes.
Season generously with salt and pepper and simmer for about 10 minutes.
Add the spinach and simmer for a further minute until wilted, then squash each potato with the back of a fork, remove from the heat and serve.
