Personally, I think YES! I did not find that berries (specifically strawberries) hold up well on the grill, even for a quick minute. I would recommend keeping the leafy greens fresh for the burgers to have the best texture and crunch. Other than that, have fun with your produce on the grill. Potatoes also make a wonderful addition when thinly sliced that can serve as a healthier swap for “traditional” sides like chips or French fries!
