Warm salads can be blooming amazing or a complete disaster. First, you have got to get your hungry guests around the table before you plate up, so as soon as their bums are on the chairs, you are tossing the warm ingredients in with the rocket leaves. Boom, boom, boom on a plate and it's in front of them.
Peel, halve, and quarter the onions then quarter again, to give you 8 pieces from each onion. Heat a frying pan and fry off the rashers of pancetta until crisp. Add a couple of lugs of olive oil to the pan, and add the sprigs of thyme, the onions, and pine nuts with a pinch of salt. Toss around and fry on a medium heat for about 5 minutes until caramelized and sweet (not black!).
Then, throw everything into a salad bowl with the rocket or any nice salad leaves. Drizzle generously with balsamic vinegar, this will make a natural dressing as it mixes with the olive oil. Serve with some shaved Parmesan over the top, you can use a potato peeler to do this. Munch away.
