Preheat the oven to 350 degrees and toast the tostada shells, about five minutes.Put the tomatoes, 1/2 cup red onion, 1/4 cup cilantro, 2 tbsp lime juice, and a pinch of salt in a small bowl and mix.Be sure to remove the tostado shells. :)Next, add the avocados, vegan yogurt, 1/4 cup red onion, garlic cloves, 2 tbsp lime juice, 1 tbsp cilantro, and 1/2 tsp salt to a blender and blend until smooth. You can add jalapeño and/or red pepper flakes for heat. You can also add more vegan yogurt to make it creamier if you wish.In a large pan, brown the beef. Drain the fat from the pan. Add 1/4 cup of water and the taco seasoning (chili powder, dried oregano, cumin, onion powder, garlic powder, smoked paprika, salt, and pepper) and stir until combined.Layer the black beans, beef, avocado crema, pico, and additional toppings of choice (I chose jalapeños) and enjoy. 🤍
