Cut the pork tenderloin into small, even pieces so it cooks quickly and browns evenly in the skillet.

Place the pork in a medium bowl. Add the lemon zest, garlic powder, soy sauce, and honey, then mix well until every piece is evenly coated. Let it sit for a few minutes while you prepare the slurry so the pork can absorb the flavors.

In a small bowl, stir together the cornstarch and water until completely smooth. Make sure there are no lumps, because this will help create a silky sauce later.

Heat the olive oil in a large skillet over medium-high heat. Once the skillet is hot, add the seasoned pork and spread it out so the pieces have room to brown.

Let the pork cook without stirring too much at first so it can develop a golden sear. After the first minute or two, stir and continue cooking until the pieces are lightly browned on most sides.

Add the crushed garlic and stir well, cooking just until fragrant. Be careful not to let the garlic burn.

Pour in the cornstarch mixture and stir continuously as it heats. The sauce will begin to bubble, turn glossy, and lightly thicken around the pork.

Keep stirring until the pork is cooked through and coated in a silky sauce. If needed, add a small splash of water to loosen the sauce slightly.

Finish with sesame seeds and serve immediately while hot. Spoon any extra sauce from the pan over the top before serving if desired.
