Spray a large baking sheet or cookie sheet with non-stick cooking spray or olive oil spray, set aside.
Combine 1/2 tsp salt, lime zest, and chili powder in a small bowl. Sprinkle all over the raw shrimp. Lay the shrimp on the cookie sheet and spritz with the non stick cooking spray or olive oil spray. Bake for 5-8 minutes or until the shrimps turn pink and curl in on themselves.
Meanwhile combine the diced avocado, lime juice and remaining 1/2 tsp salt in a small bowl.
Combine the sour cream and minced chipotle pepper in a different small bowl.
Assemble your shrimp taco bites by placing a tsp of avocado mixture in a tortilla chip, followed by a 1/2 tsp of sour cream mixture, then top with a chili-lime shrimp.
Sprinkle with the chopped cilantro. Enjoy!
These bites are best when prepared just before serving.
