In a medium bowl, combine ½ cup sour cream, 2 tbsp adobo sauce, 1 tbsp fresh lime juice and ¼ tsp kosher salt. Add 4 cups shredded red cabbage and toss to coat. Cover with plastic wrap and refrigerate until ready to use.
In a medium bowl, combine ¼ cup all-purpose flour and 2 tsp kosher salt.
In another medium bowl, whisk 2 large eggs.
To a third medium bowl, add 1 cup panko breadcrumbs.
Working with one fillet at a time, coat 4 mahi mahi fillets in flour (shaking to remove excess), then egg, and then panko. Repeat with remaining fish.
Cook Fish
Add 2 ½ cups canola oil to a 10-inch heavy-duty skillet. Line a plate with paper towels.
Heat oil over medium-high heat until a pinch of panko dropped in oil sizzles, about 6 minutes.
Add fish to skillet and cook on one side for about 4 minutes.
Carefully flip fish. Lower heat to medium low and cook until the internal temperature reaches 105˚F.
Transfer fried fish to paper towel-lined plate.
Let rest for 5 minutes. (The internal temperature will continue to rise.)
Assemble
Place sliced 1 ripe avocado in middle of each tortilla. Place 1 piece of fried fish on top, followed by ¼ of the 1 cup pico de gallo and ½ cup of your pre-made cabbage slaw.
Tuck sides of tortilla in, then roll tortilla up like a cylinder.
