Mash the avocado in a bowl until smooth. Add the water and mix until evenly combined.
In a separate bowl, whisk together chickpea flour, allspice, turmeric, salt, and baking powder.
Stir the dry ingredients into the avocado-water mixture until a thick, smooth batter forms.
Scoop the batter into the waffle iron (adjust the amount based on your waffle maker). Cook for 4-5 minutes until golden and firm.
Top with tahini drizzle, roasted vegetables, and fresh herbs.
