To make your meatballs:

Pick the rosemary leaves off the woody stalks and finely chop them. Wrap the crackers in a kitchen town and smash up until fine, breaking up any big bits with your hands. Add to the bowl with mustard, ground meat, chopped rosemary and oregano. Crack in the egg and add a good pinch of salt and pepper. With clean hands, scrunch and mix up well. Divide into 4 large balls. With wet hands, divide each ball into 6 and roll into little meatballs—you should end up with 24. Drizzle them with olive oil and jiggle them about so they all get coated. Put them on a plate, cover and place in the refrigerator until needed.
