Fill a big pot with salty water and heat it until it's vigorously boiling. Toss in the baby potatoes and let them cook for around 10 minutes, or until they're soft but still holding together. Drain the water completely, move the potatoes to a large bowl, then pop it in the fridge to cool so they’re comfortable to handle.

As the potatoes chill, start on the pesto. Put the arugula, pine nuts, garlic, Parmesan, lemon juice, chili flakes, salt, and pepper into your food processor or blender. Pulse it about 4-5 times, just enough to break it all down without making it too smooth.

Turn on the food processor at a low speed. Gradually pour in the olive oil through the top opening until your pesto is creamy and fully blended. Stop occasionally to scrape down the sides so everything mixes well.

When the potatoes have cooled enough to touch, slice them in halves or quarters depending on their size. Keep them small enough to eat easily, but firm enough to hold their shape for coating with pesto.

Drizzle the vibrant green pesto you just made over the potato pieces. Gently toss to coat everything evenly. Serve right away for a warm salad, or keep it in the fridge to chill completely before serving it cold later.
