Whilst the tray and oil are heating up, drain the tin of chickpeas, rinse, and tip onto a clean tea-towel (you could use a few sheets of kitchen paper if your prefer). Give them a really good rub to dry them well, then leave to air-dry for a few minutes – this will really speed up the cooking process as they will become crispy more quickly.
Tip them into the hot baking tray along with a small pinch of salt and some freshly ground black pepper. I say a small pinch of salt because you will be adding them to the anchovies later which are already really salty. Shake the baking tray to coat the chickpeas well in the oil, salt and pepper, then halve the cherry tomatoes and line them up down one side of the tray – you want to keep them separate from the chickpeas so that the moisture from the tomatoes doesn’t affect the crisping process. If you don’t mind the extra washing up, you can use a separate tray for this.
Put the tray in the oven and pour another glug of olive oil into a frying pan over a low heat. Finely slice the garlic and add to the pan – do not let it burn. Add the anchovy fillets and give it all a good stir. The anchovies will start to dissolve and mingle with the garlic, creating a flavoured oil that will taste amazing.
Give the broccoli a wash and slice the stems into roughly 2cm chunks (leaving the tips whole). Add to the pan along with a good pinch of chilli flakes. Keep them moving around the pan over a low heat until the broccoli is lightly cooked (the residual water from washing will slightly steam and help the broccoli to cook through), then set to one side in a warm place.
The chickpeas and tomatoes will probably need about 15 minutes but check them after 10 in case your oven is super hot. You want the chickpeas crispy (not burnt!) and the tomatoes softened and starting to catch around the edges.
Once they are done, add the chickpeas to the broccoli pan with a small handful of chopped flat leaf parsley, a squeeze of lemon juice and a grind of black pepper and give it all a good stir. Check the seasoning, but you probably won’t need more salt.
Heap the broccoli and chickpea mix into a shallow bowl, top with the tomatoes and a grating of Parmesan cheese enjoy!
