Drain and rinse a can of chickpeas. Add chickpeas to a blender or food processor along with the flesh of 2 avocados, 2 peeled garlic cloves, 2 tablespoons lime juice, 15-20 sprigs cilantro (rinsed and bottoms twisted off), 1/2 teaspoon cumin, 1/2 teaspoon salt, freshly ground pepper, and 2 tablespoons of olive oil.
Add a splash of water to the blender and combine well. Taste for seasoning, adding more salt and lime juice if necessary.
For the Cucumber Pico be sure to give all the ingredients a good rinse. Then chop 1/2 cucumber, 1 tomato, 1/4 onion, 1/2 jalapeno, 8-10 sprigs cilantro and combine with 1/4 teaspoon salt and the juice of half a lime. Taste for seasoning.
If using storebought tostadas, warm them up in the oven for 2-3 minutes or until golden brown.
Add a layer of Avocado Hummus and Cucumber Pico de Gallo to each tostada. Garnish with your choice of hot sauce, cilantro, or Cotija cheese.
Store leftover Avocado Hummus and Cucumber Pico separately in airtight containers in the fridge.
