In a small bowl, whisk together the lime juice, apple cider vinegar, honey, and chopped fresh cilantro to create the slaw dressing.
Place the shredded cabbage and carrots in a medium bowl, pour the dressing over the top, and toss thoroughly to combine.
Pat the catfish fillets very dry with a paper towel to ensure a crispy sear.
On a shallow plate, combine the almond flour, smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Dredge each catfish fillet in the almond flour mixture, pressing gently to ensure the seasoning adheres to both sides.
Heat the avocado oil in a large cast-iron or non-stick skillet over medium-high heat until shimmering.
Add the catfish fillets to the skillet and sear for 3-4 minutes per side until the crust is golden brown and the fish is opaque and flakes easily.
Serve the hot, crispy catfish immediately with a generous side of the zesty slaw.
