With a sharp knife, remove the corn from the cobs
Heat the 2-3 tablespoons of oil you’ve set aside in a large skillet, and add the corn along with a pinch of salt.
Cook for about 2 minutes, stirring frequently.
Add the bell pepper and onion, and saute for another 2 to 3 minutes, until they begin to get fragrant.
Remove the shrimp from the marinade, and add to the skillet.
Use the leftover marinade to season the shrimp and vegetables as you stir them constantly.
When they’re almost done, beat about 2 teaspoons of the lemon juice and all the lemon zest into the Greek yogourt, and adjust with salt if necessary.
Heat the tortillas in the oven.
Assemble by spooning the shrimp mixture over the middle, and topping with a dollop of lemon crema along with a sprinkle of cilantro.
