Marinate the shrimp:
Mix the lime juice, zest, extra virgin olive oil and cilantro in a small bowl. Sprinkle the shrimp liberally with garlic powder, onion powder and lightly with cayenne pepper. Pour the lime cilantro mixture over the shrimp and spread out in a single layer; let marinate for 1/2 hour.
Make the veggies:
Sauté the peppers, red onion, garlic, corn, and tomato in a small amount of oil till tender. Add the shrimp, cumin and lime and cook until done (I like when its browned).
Make the salsa:
Mix all salsa ingredients and salt and pepper to taste.
Make the cilantro yogurt:
Mix all ingredients for the yogurt together.
Toast the corn tortillas
Putting it all together:
Place shrimp mixture (3 shrimp) on top of a corn tortilla, top with desired amount of salsa and red cabbage and finish with a dollop of the cilantro yogurt dressing
