This seasonal dinner utilizes the oven for a main dish of pork tenderloin and a side dish of vegetables that are slow roasted and tossed in pesto to concentrate their flavor.
Toss cauliflower, carrots, red onions and eggplants in oil and season with salt and pepper. Spread the vegetables on a sheet pan and roast, stirring occasionally, until vegetables are golden and tender, ~35 minutes.
While vegetables roast, coat pork on all sides with spice rub. Heat a skillet over medium-high heat. Add cooking oil and then pork to heated oil. Sear on both sides for 2 to 3 minutes each, until golden brown. Pour stock into skillet, cover loosely with foil, and bake in the oven for 16 to 20 minutes or until pork reaches 145F / 63C degrees. Let rest, covered for 10 minutes.
Toss vegetables with pesto.
Slice pork and drizzle cooking liquid over the top. Enjoy with roasted vegetables on the side!
