Light yet filling, flaky grilled halibut fillets are tucked into corn tortillas and topped with crunchy vegetables and fresh herbs.
Rub fillets with oil and season both sides with salt and pepper. Heat a grill pan over medium-high. Grill fish, flipping once, until cooked through, about 4 minutes per side. Flake fish into large pieces, discarding any bones.
Toast corn tortillas over a kitchen burner using tongs or wrap in parchment-lined foil and heat in oven, 5 minutes. Divide fish evenly among tortillas and top with cabbage, radishes, cilantro, and scallions. Season with salt. Serve with yogurt and lime wedges.
