Chimichurri Grilled Skirt Steak

"Those of use who live in Florida don't generally do it for the summer. I mean, the swimming pool is warm most of the year, so that's great - but the real reason we hang around is for the beautiful weather that finally rears its head come fall. Fall means all outside all the time. It's hiking, and picnicking, and gardening, and grilling, and WHOOP WHOOP we love Florida! And I don't know what it is about being outdoors all the time but it makes me want to eat all the delicious colorful foods. Ripe red tomatoes? Yes! Juicy green grapes? Yes! A gorgeous skirt steak smothered in chimichurri sauce? Yes, yes, YES!"
