In a blender or food processor, combine the first 5 ingredients. Set aside.
Shrimp:
Toss to coat the shrimp pieces with the olive oil and spices + salt & pepper to taste.
Heat your skillet on medium high and toss in shrimp when hot. Cook on medium heat for a few minutes. These should cook fast. Toss around the pan and make sure they cook evenly. Remove when done.
Add some avocado oil to your pan and fry up the tortillas on each side until golden and crispy. Top with your cheese to melt and then the shrimp and rest of your toppings.
Notes
You can use Greek yogurt to make the crema lighter.
