Halve the tomatoes and toss them in a bowl with the oil, chilli flakes, rosemary and half of the garlic clove, finely chopped. Add salt to taste and chill in the fridge for 1 hour.
Slice the bread and grill or toast it till crisp. Take the other half of the garlic clove and rub it over the slices of toasted bread.
Divide the lard among the toasted bread. Top with the tomato mixture. Sprinkle with ground pink peppercorns. Serve.
