Rinse your potatoes and give them a little scrub to remove any dirt from the skins
Pop them into a pot of salted boiling water - allow them to cook for around 15 minutes or until a fork can pierce through relatively easily (with just a little resistance)
Drain the potatoes and return to the pot
Add everything else (except the pesto) - olive oil, garlic powder, onion powder and salt - stir well to coat the potatoes
One at a time, add potatoes to a flat oven proof baking tray/dish and begin the 'smashing' process
Using the bottom of a thick-bottomed glass or the back of a large spoon, press firmly but slowly onto each potato until you feel it start to give, press with just enough force to flatten it a little and then release the tool you're using to press down
Repeat until all of the potatoes are smashed!
Pop the potatoes in to the oven for about 20 minutes or until they're bubbling a little and crispy
Remove potatoes from the oven, dollop with the pesto and service with just about anything!
