Zest and juice one lime, separate 1/2 of the juice and zest into a large bowl for the marinade. Reserve the other 1/2 of the juice and zest and set aside in a medium bowl for the Chipotle Lime Sour Cream.
To the large bowl, add the remaining marinade ingredients - chili powder, garlic powder, salt, pepper, tequila (if using), and olive oil. Add shrimp, mix, and refrigerate to marinate while prepping salsa.
For the Strawberry Avocado Salsa, chop strawberries, cilantro, red bell pepper, add to medium bowl. Finely dice jalapeno and red onion, add to bowl, and toss to mix. Chop avocado, and add to salsa. Squeeze juice of one lime over avocado, sprinkle salt, and gently toss to coat (being careful not to brusie or mash the avocado too much).
Remove shrimp from marinade and place on a grill pan or skillet over medium high heat. Cook about 5 minutes per side or until opaque (and slightly charred if using grill pan).
While shrimp cooks, prep Chipotle Lime Sour Cream. Dice chipolte pepper (removing seeds if desired to reduce heat). Add chipotle and sour cream to reserved lime juice and zest. Stir to mix.
When shrimp is cooked, remove from pan and set aside, covered.
Add corn tortillas to grill pan or skillet a minute or two per side until slightly warmed.
Serve tacos by topping corn tortillas with shrimp, strawberry avocado salsa, and chipotle lime sour cream.
