Mix up the sauce ingredients and set aside in a small serving bowl.
Mix up the spices for the shrimp then toss the shrimp in with the spices.
Mix the avocado and tomato salsa together and set aside in a small serving bowl.
Heat a skillet over medium heat (I used a cast iron skillet). Coat with a small bit of oil, then cook the shrimp about 2 minutes per side, until cooked through. Remove to a small serving bowl.
Wipe the skillet and then heat the corn tortillas until warmed through, one at a time.
Serve everyone 1 or 2 corn tortillas and let them build their own tacos.
