Cook the spaghetti following the packet instructions.
Meanwhile, heat the oil in a large frying pan and add the broccoli, chilli and zest. Cook on a medium heat for 5 minutes, stirring often to prevent sticking.
After 5 minutes add the cherry tomato halves to the pan. Cook for a further 1-2 minutes until they begin to soften and the broccoli is tender. Squeeze in the lemon juice and give everything another good stir. Remove from the heat.
Drain the spaghetti and add to the pan with the cooked broccoli and tomatoes. Toss well to combine everything and divide between four plates. Serve with some grated cheese, if you like.
For a meaty pasta, chop 4 pork sausages into 2cm (¾in) pieces and fry for 12-15 minutes until browned. Add to the pan at the same time as the broccoli, chilli and lemon zest and stir.
