Place your slices of whole grain bread in the toaster and toast until golden brown.
While your bread is toasting, prepare your avocado and chickpea spread. In a medium bowl, add your drained chickpeas and the flesh of the ripe avocado.
Use a fork or a potato masher to smash the chickpeas and avocado together until you achieve a chunky paste.
Season your chickpea and avocado mix with salt, pepper, and a squeeze of fresh lemon juice. Mix well to combine.
Once your bread is toasted to your liking, spread a generous layer of the chickpea and avocado mix onto each slice.
Top your smashed chickpeas avocado toast with slices of fresh cucumber, pickled cucumber, and pickled jalapeños. You can add as much or as little as you like, depending on your preference.
Serve your vegan smashed chickpeas avocado toast immediately for the best texture and flavor.
If you've made the chickpea and avocado mix in advance, store it in an airtight container in the refrigerator and assemble your toast just before you're ready to eat.
