Drain a 200 g can of chickpeas, reserving the liquid. Divide the chickpeas into two equal portions of 100 g each.
For the tomato hummus: in a blender or food processor, combine one portion of chickpeas with 4 oil-packed dried tomatoes, 1 garlic clove, 1 tbsp oil from the tomato jar, 1 tbsp lemon juice, and 1 tbsp tahini. Blend to a smooth paste, loosening with the reserved chickpea water a tablespoon at a time until you reach a creamy consistency. Season with salt and pepper.
Transfer to a bowl. Finely chop the 2 remaining dried tomatoes and scatter over the top.
For the avocado hummus: in the cleaned blender, combine the second portion of chickpeas with the pitted flesh of the avocado, 0.5 bunch of basil leaves, and a splash of the reserved chickpea water. Blend to a smooth paste and season with salt and pepper.
Loosen further with chickpea water if needed. Transfer to a bowl and finish with a sprinkle of dried chilli flakes.
