Watercress Pesto is a delicious and nutritious alternative to the classic basil version but can be used in the same way. Watercress is high antioxidants and vitamins C and K and it contains a large number of dietary nitrates which help to boost blood vessel health, making it a healthy heart food.
½ cup flaked, lightly roasted almonds
20g grated Parmesan
Juice and zest of ½ a lemon
1 tablespoon white balsamic vinegar
Salt and pepper
Place all ingredients except salt, pepper and olive oil in a food processor. Blitz the ingredients whilst simultaneously adding olive oil until you reach the consistency of a classic basil pesto. Check the seasoning and add salt and pepper if needed (watercress is quite peppery and parmesan is salty so you may not need salt and pepper).
