### Instructions
1. **Prepare the Lettuce:** Wash your chosen lettuce thoroughly and pat it dry. Roughly chop or tear it into bite-sized pieces. Set aside.
2. **Heat the Wok/Pan:** Heat your wok or large skillet over medium-high heat. Add the cooking oil and swirl to coat the pan.
3. **Sauté Garlic:** Add the minced garlic to the hot oil and stir-fry for about 30 seconds until fragrant. Be careful not to burn it.
4. **Add Lettuce:** Immediately add the chopped lettuce to the hot pan. It will look like a lot, but it will quickly wilt down.
5. **Seasoning:** Pour in the soy sauce, oyster sauce (if using), sugar (if using), and white pepper (if using). Add the splash of water.
6. **Stir-Fry Quickly:** Using tongs or a spatula, quickly stir-fry the lettuce for 1-2 minutes, tossing to ensure all the lettuce is coated with the sauce and softens slightly but retains a crisp texture. Do not overcook!
7. **Serve:** Transfer the stir-fried lettuce immediately to a serving dish. Garnish with sesame seeds if desired. Serve hot as a healthy and flavorful side dish.
### Short Tips
* **Don’t overcook!** The key to delicious stir-fried lettuce is a quick cook time to retain its crispness. It should still have a slight bite.
* **Dry lettuce is essential.** Watery lettuce will steam instead of stir-fry, leading to a less flavorful result.
* **Customize your flavor.** Feel free to add a tiny pinch of red pepper flakes for heat, or a drop of rice vinegar for a tangy kick.
* **Experiment with lettuce types.** While romaine is great, iceberg will offer a super crunchy texture, and butter lettuce will be more tender.
* **Serve immediately.** This dish is best enjoyed fresh from the pan.
