Ingredients:
- 1 lb lean ground beef
- 1 tbsp olive oil
- 1/2 small onion, finely diced
- 2 cloves garlic, minced
- 2 tbsp tomato paste
- 1 tsp apple cider vinegar
- 1 tbsp chili powder
- 1 tsp ground cumin
- 1/2 tsp smoked paprika
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/4 cup water or beef broth
- 8 corn tostada shells
- 1 cup refried beans
- 2 cups shredded iceberg lettuce
- 1 cup shredded Monterey Jack or Queso Fresco
- 1/2 cup Mexican crema or sour cream
- 1 medium avocado, sliced or diced
- 1/4 cup fresh cilantro, chopped
- 1 small red onion, finely diced
Instructions:
- Heat the olive oil in a 12-inch skillet over medium-high heat.
- Add the ground beef, breaking it apart with a spatula, and cook until browned and no longer pink.
- Stir in the diced onion and garlic, sautéing for 2-3 minutes until the onion is translucent and fragrant.
- Push the meat to the sides of the pan, add the tomato paste to the center, and cook for 1 minute until it reaches a deep mahogany color.
- Stir in the chili powder, cumin, smoked paprika, salt, and black pepper.
- Pour in the apple cider vinegar and water or beef broth, stirring well and simmering until the sauce thickens and coats the beef.
- Spread a thin, warm layer of refried beans across the surface of each corn tostada shell to create a moisture barrier.
- Layer the seasoned beef over the beans, followed by shredded lettuce, shredded cheese, a drizzle of Mexican crema, and avocado slices.
- Garnish with chopped cilantro and diced red onion before serving.
