Put the tomatoes in a roasting pan and drizzle over the olive oil. Sprinkle over the basil and season well. Cook for about 30 minutes or until just soft.
Meanwhile, blanch the asparagus for 1 - 2 minutes then refresh in cold water and drain well.
Mix the dressing in a screw top jar and shake well. Arrange the tomatoes and asparagus onto 4 serving plates and pour over the dressing.
