Seasoned minced beef is piled onto crispy tostada shells with fresh toppings that add a touch of sweetness alongside the savory meat. The flavor profile draws on New Zealand-style beef seasoning combined with the crunch and structure of a traditional Mexican tostada. Everything is ready in about 30 minutes.
Heat the olive oil in a large skillet over medium heat. Add the minced beef and cook, breaking it apart with a spatula, until browned and cooked through, about 5-7 minutes.
Stir in the ground cumin, ground coriander, and tomato paste. Cook for another 1-2 minutes until the spices are fragrant and the beef is well-coated.
Add the diced tomatoes and let the mixture simmer for 5 minutes. Season with salt and pepper to taste. The mixture should be flavorful and slightly thickened.
In a separate bowl, combine the kiwi, avocado, red onion, and cilantro. Add the lime juice and toss gently to mix. This will be the fresh and tangy topping.
To assemble, place an even amount of the beef mixture on each tostada shell. Top with the kiwi-avocado salsa. Serve immediately.
Notes
For a spicier kick, consider adding diced jalapeños to the beef mixture. Vegetarians can replace the beef with cooked black beans for a plant-based alternative.
