Boil potatoes for about 10-15 minutes until they are soft enough to mash, but still firm.
If you’re using frozen green peas, thaw them in hot water and microwave for 40 seconds.
In a blender, add the garlic, olive oil, red wine vinegar, kosher salt and basil and pulse until the ingredients turn into a paste.
In a large bowl, add potatoes and pour the dressing over. The potatoes can be used hot or cold, though they absorb the flavor better when they’re warm.
Lightly mash the potatoes so they’re a little creamy but we still want to leave a good amount of chunks. Add green peas, parmesan and mix well.
Sprinkle chives and serve warm or cold.
Notes
Keep the leftovers in a storage container and refrigerate for up to 3 days.
