It’s easy to fit an entire meal in a pan when you roast your favourite meat over a bed of vegetables. This simple method is infinitely adaptable to the contents of your fridge and the harvest of the day. Simplicity is the goal and just about anything goes. Here, cauliflower, leeks, and apples slowly roast, absorbing the juices and flavours of cinnamon-crusted pork tenderloin. The toughest part is leaving leftovers! – Farmhouse Vegetables, Michael Smith, Penguin Canada.
Preheat the oven to 350°F (180°C). Turn on the convection fan if you have one.
In a large roasting pan, gently toss together the cauliflower, leeks, apples, cumin seeds, coriander seeds, and vegetable oil. Lightly season with salt and pepper.
In a medium bowl, whisk together the brown sugar, cinnamon, salt, and pepper. Roll the pork tenderloin in the mixture to evenly coat. Nestle the pork in the centre of the vegetables. Roast, gently shaking and settling the pan once or twice, until the vegetables and pork are tender and lightly browned, 45 minutes or so. The pork is done when a digital or quick-read thermometer registers at least 145°F (63°C) in the thickest part of the meat. Remove from the oven and rest a few minutes. Thinly slice the pork and return it to the pan with any accumulated juices. Stir together gently before serving.
