Preheat the oven to 200°C conventional (180°C fan-forced). Line a baking tray with baking paper.
Place the cherry tomatoes on the tray, drizzle with 1 tablespoon of the olive oil, sprinkle with the brown sugar and season well. Roast for about 20 minutes until they start to colour. Remove and set aside.
In a large pot of boiling salted water, cook your pasta according to packet instructions until al dente. Drain, reserving about 1/2 cup of the pasta water, and set aside to keep warm.
Heat a large frying pan over high heat. Add the prosciutto and cook, stirring, for about 2–3 minutes until crispy and browned. Remove and set aside.
In the same frying pan, add the remaining tablespoon of olive oil and the garlic and fry over medium heat for about 2 minutes. Add the chilli and lemon juice and cook, stirring, for a further 2 minutes. Add the cooked pasta to the pan, along with a little of the pasta water, and stir to coat. Add the roasted cherry tomatoes, spinach, basil and bocconcini. Toss gently and season well.
To serve: Add the pasta to bowls and top with the crispy prosciutto and some grated parmesan, if desired.
