Preheat skillet. Lay strips evenly over skillet. Keep the heat at medium-high until the skillet is hot and the meat begins to cook. Once the fat starts to render, turn down to medium/medium-low heat.
Stir the meat, so it cooks evenly. (You may need to continue adjusting the heat up and down, depending on your stovetop, pan, etc.)
Once the side pork is brown and crispy to your liking, remove from pan and drain on paper towels. Serve immediately.
Save grease and pan for future use (if desired).
