Place the peas in a microwavable container with 60ml of water and cook for 1½ minutes on High. Alternatively, briefly cook to manufacturers instructions, drain then add 60ml water. Allow to cool. Using either a hand blender or liquidizer, blitz the peas until they are smooth. Add the avocado and lemon juice, blitzing again to your desired consistency. Fold in the chopped tomatoes, onion and coriander. Serve at room temperature with a selection of raw vegetables and taco chips.
* do choose tender, good quality peas which only require the briefest of cooking to al denté.
