Start by cooking the rice according to package directions or your methodology of choice.
In a mortar and pestle, crush the garlic, lemongrass, and thai chilis until a rough paste forms. Combine in a bowl with 1 tablespoon of Fish Sauce and marinate the shrimp in the mixture for 5-15 minutes.
Add in the shrimp and cook in a single layer for 1-2 minutes each side, then remove the shrimp from the skillet. This is to avoid overcooking the shrimp.
Begin to sauté the minced garlic, onions, mushrooms, and more thai chilis in the same pan with cooking spray.
Once the vegetables have softened, add in the cooked rice along with the soy sauce, remaining 1 tablespoon of fish sauce, and white pepper and mix thoroughly.
Move everything to one side of the pan, spray the pan with cooking spray, and add in the egg. Once the egg begins to settle, begin to mix it into the rice.
Add in the shrimps, remove from heat, and garnish with cilantro and scallions. Time to enjoy your delicious meal!
