Thaw the peas and broad beans in warm water, then rinse the husks of the broad beans.
Grate the pecorino cheese, pluck the mint leaves and put both in a tall mug with peas, beans, pecorino cheese and olive oil and puree. The more olive oil you add, the smoother the spread will be.
Season with lemon juice, salt and pepper.
Rub the halved garlic clove over the bread slices and pour the pea spread on top.
