Pre-heat the oven to 200C. Par-boil your new potatoes then drain and toss in the lemon zest and 1 tbsp olive oil in a baking tray. Season with salt and pepper then pop in the oven for 20 minutes or until the potatoes are tender and golden around the edges.
Blend the watercress, lemon juice, garlic and 2 tbsp olive in the food processor. Season with salt and pepper, you might want to add some more lemon juice for an extra zing or olive oil if it’s a little stiff.
In a small frying pan over a medium heat, toast your flaked almonds, this will only take a couple of minutes before they start to turn brown so keep an eye on them.
Steam the broccoli then tip your roasted new potatoes onto a large serving dish and place the broccoli over the top. Dress with your watercress pesto and toasted almonds then mix everything together and serve!
