How to Make It
Season the salmon with the cumin and ¼ teaspoon each kosher salt and black pepper. Cook in 1 tablespoon of the oil in a large nonstick skillet over medium-high heat until opaque throughout, 4 to 6 minutes per side; flake.
Meanwhile, toss the cabbage and avocado with lime juice, the remaining oil, and ½ teaspoon kosher salt.
Serve the salmon in tortillas with the slaw and cilantro.
