Add all ingredients besides buns to a large mixing bowl. Using your hands, thoroughly combine mixture.
Form in to 2 - 4 patties, depending on how large you'd like your burgers.
Grill burgers at about 400 degrees until cooked thoroughly. The proper internal cooking temperature for ground chicken is 165 degrees. On my grill, this takes roughly 10 minutes.
As the burgers rest, lightly grill brichoe buns until lightly charred, about 2 minutes.
Spread buns with mint chimichurri, top with burger, and enjoy!
For the mint chimichurri:
Add all ingredients to a food processor, pulsing to combine. Start by adding just half of the called for amount of olive oil, adding more to adjust the consistency to your liking. Keep in mind we want this to be more of a spread, so thin with caution!
