- Cook the Onions:
- In the same skillet, reduce the heat to medium. Add the onion rings and sauté until they are soft and translucent but not fully caramelized. This should take about 2-3 minutes. Remove the onions from the skillet and set them aside with the pork.
- Simmer the Sauce:
- Pour the reserved marinade and water into the skillet. Bring it to a simmer and let it cook for about 1-2 minutes to reduce slightly. If you find the sauce too tangy, you can add a teaspoon of sugar to balance the flavors.
- Combine and Finish Cooking:
- Return the pork slices and half of the onion rings back to the skillet. Let them simmer in the sauce for another 5-7 minutes, or until the pork is fully cooked and tender. Adjust the seasoning with salt and pepper if necessary.
- Serve:
- Transfer the pork bistek to a serving platter. Top with the remaining onion rings and garnish with additional calamansi or lemon slices if desired. Serve hot with steamed rice.
