Soft Shell Mexican Tacos

For the GUACAMOLE, pour out any water that is sitting on top of your guacamole and don't worry if a few softened bits of guacamole escape in the process. CHEFS NOTE: the water is just to prevent it from discolouring. Place it in a bowl along with a squeeze of lemon, a drizzle of olive oil, the yogurt and a generous amount of seasoning. Mix well and season further to taste.
