When you are ready to eat, cook your vermicelli to the time indicated on the package (usually 3 minutes), then drain and rinse well with cold water. Set aside. Prepare your vegetables. In the photo, I used quick pickled cucumbers, purple cabbage, lettuce, cilantro, lime, and fried onions.
To make quick pickled cucumbers, thinly slice 1/4 of an English cucumber, then toss with 1 teaspoon salt and 1 tablespoon sugar. Let sit for 15 minutes, then rinse in cold water.
Heat a large nonstick skillet with 1 tablespoon of oil over medium heat. Fry your remaining 1 tablespoon of minced lemongrass until crispy and golden brown, then drain and set aside, reserving the oil.
Add the marinated meat to the skillet and fry until well charred on both sides. You may need to do this in batches depending on the size of your nonstick skillet.
Arrange vermicelli, vegetables, and beef in a bowl. Toss with 1/4 cup of the fish sauce, then top with fried lemongrass, fried shallots, a squeeze of lime, and sliced chilies, as desired.
