Mix all ingredients in a bowl, add shrimp and marinate for 20-30 minutes. While prawns marinate, prepare cabbage slaw and sauce.
Cabbage Slaw:
Whisk greek yogurt, olive oil, lime juice, cilantro in small bowl until combined and creamy.
Pour over remaining ingredients in a larger bowl and toss well.
To cook prawns:
Heat 1 tbsp olive oil in large skillet on medium-high heat.
Add prawns (with marinade mixture) and cook 2-3 minutes, turning once, until opaque in the center.
To assemble tacos:
We prefer to warm the tortillas individually in a small skillet or on the stove but you can also wrap them in a damp paper towel, then foil, and warm in oven on 250 degrees for 10 minutes.
Layer the cabbage slaw, prawns, and taco sauce in the tortillas and top with fresh cilantro, fresh avocado, and lime.
