Guy Fieri has a real cast of characters over for a cook-off, and the first challenge is Guy's Grilled Lamb Ribs, coated in a toasted spice rub, slow-roasted over a bed of onions then finished on the grill with a rich pan sauce. If your mouth is watering now, just wait until you try them with Apricot Mint Chimichurri, a bright, sweet-savory herb sauce that takes those ribs to the next level. On the side, how bout some Smashed Tri-Color Potatoes? Baked under a layer of Parmesan cheese, they're creamy inside, golden and crispy on top.
