In a shallow bowl, combine shrimp (prawns) with all of the spice ingredients, and rub into the shrimp until evenly coated. Heat a large pan/skillet on medium heat and add the olive oil. Saute the shrimp/prawns and the Asparagus while turning occasionally until the shrimp/prawns and asparagus have started to change colour and are just cooked (about 5 minutes).

Step 3
Combine the yogurt in a bowl with the lemon pepper, lemon juice (if using), water and salt. Mix well to combine.
