Preheat the oven’s broiler then line a rimmed baking sheet with foil and set aside.
Rub salt, pepper, baking soda, and avocado oil onto the tenderloin. Place the tenderloin onto the foil lined baking sheet and tuck the thin end of the loin under itself so that it is an even thickness.
Broil on hight for 5 minutes then flip and broil another 8-14 minutes, or until the meat registers 125ºF (there is significant carry over cooking so pull it from the oven before the usual cooking temperature of 140ºF). Remove from oven, tent with foil, and rest for 10 minutes before slicing and serving.
While the pork is broiling, make the sauce. Stir together the balsamic, allulose and salt in a small pot. Simmer until reduced by half and the mixture is syrupy. Set aside.
Prepare the salad. Combine the oil, lemon zest, and juice. Add the asparagus and toss together to coat evenly. Season to taste with salt and pepper. Scatter goat cheese over top.
Slice the pork to serve, top with balsamic sauce, and plate with the asparagus salad.
