The first time someone cuts into one of these at the table, the conversation stops. Layers of bacon, prosciutto, mushrooms, and melted provolone spiraled inside seared flank steak, perfectly rolled and sliced, with a hard char on every side. After the first bite, expect the conversation to take a few minutes to pick back up again; these are that good. <\/p>\n Our trick for the ultimate flank steak pinwheel is we grill them sliced instead of as a whole log Each cut gets a direct sear instead of steaming inside its own roll. The steak cooks faster, the cheese melts without burning, and you can pull individual pieces to different doneness if you\u2019re cooking for people with different preferences. The slice down the middle when you cut into it, is exactly what you want it to look like.<\/p>\n The filling doubles down on big, rich flavors. Rendered bacon, prosciutto, mushrooms, umami, spinach, and pesto. It\u2019s a lot, but every layer has a job, and the combination is insane. Just know, once you make this for the company, they will ask for it again. <\/p>\n These are rich and layered, so they want a side that cuts through rather than stacks on. An arugula salad dressed with lemon and olive oil works because the bitterness clears the palate between bites. Garlic mashed potatoes or a crusty bread make sense if you are going full comfort food.
