Make the pizza crust as per the instructions in the recipe. Preheat oven to 200 degrees C (390 degrees F). To make the sauce, mix 1 tbsp oil and all other sauce ingredients in a bowl with a whisk. Spread the sauce (but save 3-4 tbsp) on the pizza crust and put the pizza in the oven for 10 minutes.
Heat 1 tbsp oil in a skillet, add the remaining 3-4 tbsp of sauce and the chickpeas and fry for 3-5 minutes over medium heat.
Spread the chickpea mixture and the vegan cheese sauce onto the pizza and put it back into the oven for another 10-15 minutes (or until crispy). Peel the avocado, remove the stem, and cut it into pieces and put it on the pizza right before serving. Season again with sea salt/pepper/spices if desired. Enjoy your delicious avocado chickpea pizza!
