Prepare potatoes and place into Varoma dish. Pour 1 litre of water into the Thermomix bowl. Steam 25-30M/Varoma/speed 3 until cooked. Set aside in a large salad bowl.
Meanwhile prepare pesto and add to the large salad bowl.
Boil eggs in enough water just to cover for exactly 11 minutes (from cold water to finishing) on a medium high heat. Set aside to cool completely before peeling and halving. OR, if you are lucky enough to have the TM6, use the egg boiling feature to hard boiled.
Gently toss all ingredients together except avocado. Garnish with pine nuts and basil. Add avocado.
This salad will soak up the pesto over time if not eaten all at once. Add more EVOO and/or lemon juice to loosen the salad if re-serving later.
