Season the ribeye steaks with your favorite coarse seasoning, drizzle with avocado oil, and rub on both sides. Add fresh rosemary sprigs.
Heat your grill to its highest temperature (500-600°F). Grill each side for 3 minutes for medium doneness.
Serve with one or more of the optional fall side dishes: crispy Brussels sprouts with kimchi sauce, grilled acorn squash with chimichurri sauce, or baked sweet potatoes with butter and smoked salt.
