Combine the shrimp in a bowl with olive oil, lime zest, minced garlic, paprika, chili powder, red pepper flake and 1/4 teaspoon salt. Toss to combine and set aside to marinate for 15 minutes.
Toss the cabbage with jalapeno, 1 tablespoon of lime juice and a pinch of salt, set aside.
Warm tortillas in a skillet over low heat, flipping occasionally.
Heat a large skillet over medium high heat. When hot, pour the shrimp in. Sear on one side for 1-2 minutes, flip and sear on the other side until pink all the way through and no longer opaque, 1-2 minutes. Remove from heat.
To assemble tacos, layer two tortillas on top of each other. top with lime slaw, a few shrimp, and some avocado. Top with some salsa and a squeeze of fresh lime.
Makes 8 tacos. Plan for 2-4 tacos per person depending on how hungry they are! We usually eat two per person. You can use more or less jalapeno to taste. I didn't want the slaw to be very spicy so I only used a little bit.
