Soak the skewers for at least 30 minutes in water to prevent them from burning on the grill.
Place scallops on skewers so the widest surface of the scallop lie face down on a dish. 1 lb scallops should yield about 4 skewers.
Whisk together avocado oil, salt, pepper, and thyme and pour over the scallops.
Marinate in the fridge for 30 minutes to 1 hour.
Preheat your grill to high.
Grill any vegetables you'll be serving before the scallops.
Place the scallops on the grill and cook for 2-3 minutes on each side, using a wide spatula to flip them.
They are done when they are opaque and lightly charred on both sides.
Take them off the grill, sprinkle with lemon juice, and serve immediately.
