When you want a change from the usual tacos, when you want dinner on the table in just 20 minutes, this is the recipe you need. Our zesty tacos have a spicy beef filling with red cabbage, avocado, and sour cream.
In a large bowl, mix beef with lime juice and zest, pepper flakes, garlic, and 1 teaspoon salt. Heat a large nonstick skillet over high. Add beef mixture and cook, stirring occasionally, until browned, about 7 minutes. Add cabbage and season with salt. Cook, stirring occasionally, until cabbage is wilted, 2 to 4 minutes more.
Fill tortillas with beef mixture. Serve with accompaniments and lime wedges.
