Place the zucchini, capsicums, and garlic in an even layer on a roasting tray. Drizzle with the olive oil then toss with your hands to coat. Roast for 20-30 minutes, until soft. If using, sprinkle over the almonds then place back in the oven for 5 minutes, until the almonds are toasted and fragrant. Cool.
In a blender, squeeze out the garlic from the skins and add the roasted vegetables, nuts, chickpeas, tahini, olive oil, smoked paprika, and blend until your desired consistency – I like mine slightly chunky. Add a little more olive oil if its too thick.
