There are so many awesome things to post but I'm pretty sure the best thing that has ever been cooked is a grilled leg of lamb roast, butterflied and marinated over night and then grilled over medium heat to perfection. (By perfection I mean DON'T OVER GRILL IT)
Marinade can vary some but should generally contain some combination of the following:
Onion, garlic, rosemary, lime zest, orange zest, apple cider vinegar, olive/avacado oil, salt, pepper
