This is the kind of dinner that looks so pretty, you might assume it would take a long time to cook, but its a deceptively easy recipe. First, youll roast the beets and then toss into a fresh and herby arugula salad thats studded with pistachios. Meanwhile, the entire pork tenderloin roasts alongside, meaning that you have time to get life together after a busy day. If youre really short on time, you can buy pre-cooked beets at most supermarkets, however they will be more expensive than roasting your own.
