TOMATO SALAD

This is a salad I make every Christmas. Its taste, colours and freshness reflect the festive season.
800 grams mixed tomatoes eg yellow, black, red cherry,
Roma, beefsteak
sea salt and pepper
Gremolata:
½ small red onion, very thinly sliced
finely grated zest ½ orange and 1 lemon
2 tablespoons each finely chopped
flat-leaf parsley and mint
1 clove garlic, finely chopped
To finish:
olive oil
sea salt and pepper
150 grams ricotta
small black olives
METHOD:
Roughly chop the tomatoes, keeping them in good-sized pieces. Arrange on a serving platter, drizzle with olive oil and season with salt and pepper.
Gremolata:
Soak the onion in a bowl of cold water for 10 minutes. Drain and squeeze dry in a paper towel. Combine with the other ingredients in a bowl.
To finish:
Spoon the ricotta in small dollops over the tomatoes. Scatter the gremolata over and then the olives (chopped if too big).
