Keto Greek Gyro Style Pork

Put pork loin on a plate, and place in the freezer for approximately 1 hour, or until it is firm to the touch. Put meat on a cutting board, and using a sharp knife, remove and discard any skin, then slice the meat thinly against the grain, into 1/2-inch slices.

Make the marinade. In a large bowl, whisk together the lemon juice, 1/4 cup olive oil tomato paste, and garlic into the marinade, then add 1 tablespoon of the paprika, along with the salt, pepper and oregano leaves. Whisk again, scatter sliced onions on top, then place the sliced pork into the marinade, toss to combine and cover and refrigerate the meat for at least one hour and up to overnight.

When ready to cook, heat the oven to 450. Use the remaining tablespoon of olive oil to grease a rimmed sheet pan. Remove the pork and onion from the marinade, and place on the pan, spreading everything evenly across it.

Put the pork in the oven, and roast until it is browned, crisp at the edges and cooked through, about 30-40 minutes. Check the meat at around 20 minutes to see how much liquid is in the pan. If there is a lot, remove the pan, and pour off all but a few tablespoons. Remove the finished pork from the oven, allow it to rest for a minute or two before serving.
