Method

1. Heat a large non-stick frying pan over high heat. Add beef and cook, stirring to break up lumps, for 3 mins or until cooked through.
2. Stir in flour, then stir in ⅓ cup (80ml) water. Cook for 2 mins or until sauce thickens slightly and coats beef. Season with salt.
3. Spoon beans over tortillas. Top with the beef mixture, lettuce and tomato.

Serve with shaved red onion, crumbled fetta, guacamole, coriander leaves and lime wedges
